Athlon II (Regor) In the house! - UPDATED -Underclking+Power consump

** UPDATED AGAN with UNderclocking an Power consumption.- see below**

Picked one up a Athlong II X2 250 today.

Doing a full review on the chip atm that i'm going to post on another site,

I'll post direct Windsor K8 CLOCK to CLOCK comparisons for us curious folk, as well (will be the FIRST time we can actually do an apples to apples comparo of the two Uarchs [K8 vs K10] without differing cache structures) so i'm looking fwd to getting into that (nerd)

Anyway thought I'd post some stocko performance, and info for now :

Specs.

TDP: 65w (vs 80w for the PHII X2's)
Stk clock 3.0Ghz
Stk Vcore 1.35v
Cache: 2x 1MB L2 no L3
NB clock: 2000Mhz

http://img22.imageshack.us/img22/3672/athlon250stk.png

Thoughts:

* New 65w Heatsink is TINY.. pic's coming when I find my god damn card reader.

* Despite, runs very cool @ stock. with Fan speed increase minimal at full load

*Super pi performance appears about on par with or slightly faster than old Agena.. not sure about the others.

***CPU-Z needs an update Mr CPU-Z man (can't remember his nick :p:)

EDIT.. Added Die Shot's

http://img46.imageshack.us/img46/3083/regorcomp.jpg

Estimated Die Size ~110mm2

UPDATED:

out of box stock/stock comparison with its predecassesors..

Note, NOT ane exact uARCH comparison, that will be RE-Run at 2.8ghz +2.8ghz sync NB

Motherboard:
Gigabyte GA-MA770-US3
RAM:
2x1GB Crucial Ballistix @ DDR2-800 5-5-5-18
Video: ATI HD4890 OC @ 950/1020

HDD: SEagate 320GB 7200.1
PSU: Seasonic 550w

UPDATED..

K8 vs K10 comparison.

OK, so the purpose of this is to finally take a look at what core level improvments were made in the evolution from K8 to K10. Since barcelona we've had a different Cache hierarchy (wiht 2MB + of L3 cache), and independtently clocked northbridge.

Fot this test I've matched the two CPU's clock speeds, and memory speeds to (finally) bring a comparison between the two.

Of note though is the following:

this uARCh is unofficially known as K10.5. In this revamp of the core, certain applications, most evident in POV RAY gained substantial extra performance since Phenom 1 /Barcelona, so this is obviously included in the results.

secondly. the K8 runs only Ganged memory mode. This CPU or even the MOBO for whatever reason is unable to run in ganged mode, so all tests had to be run in Unganged.

apart from that though, i've done my very best to match everything else. CPU's were swapped over and all RAM timings and clock speeds verified 100%. As follows:

CPUs:

AMD X2 6400+ Stepping F3. downclocked
AMD Athlon II X2 250 C2. Downclocked.

* Clockspeed 200 x 14 (2800Mhz
* NB speed (K10) 200x14 (2800Mhz)
* DDR2: 400Mhz (standard divider for the K8, 1:2 multi for K10)
- timings 4-4-4-15 2T. With identical subtimings.

Hypertransport: stock for K8. downclocked to 5x (1000Mhz) for Regor.

All settings verified in CPU-Z (i forgot to take regor's ss, will post later)

RESULTS:

http://img188.imageshack.us/img188/2460/k10vsk8.png

Here I've split the % advantage Averages into catagories.. my reasoning as follows:

1st Average: no weighting of results. A plain average.

2nd Average: Mandrelbot removed from the avg..

Mandelbot benchmarks have recieved a massive increase in performance with K10. It may be just SSE enhancments, but it's a huge improvment. As its no indicative of overall performance i've classed it as a very large bottleneck improvment, or optimisation.

3rd average:

There are several other benchmarks that gained a huge boost from K10 . It's perfectly valid to keep these results in the average, however the majoirty of benchmarks show lesser improvements. I've made the cutoff at 30%. this is purely to segregate legacy/ commonplace code improvements.

Please Discuss! :D

UPDATE: UNDERCLOCKING AND POWER CONSUMPTION

Notes etc:

Power measured @ the wall. PSU is a 550w S12+ with PFC, so power readings should be reasonably accurate..

NO CPU reading taken as a reference, obviously it's not to be taken TOO seriously as the memory, chipset at the least will probably be in a lower power state with no CPU, but it at least gives a worst case idea.

Saw the RAM timings and knew it was a gigabyte board, didn't even have to read anything :D

lets see some tests against some of the K8 chips!

what about some overclocking? does it do 4 Ghz easily?

Looking forward to your report. :up:

Finally an energy-efficient offering from AMD, hopefully it'll match-up nicely with E5x00's in performance-per-watt department.

LOL Indeed.. typical wtf timings I get at default with my Ballistix.. go go gigabyte.

I dunno about 4 gig, but with the miniscule stock heatsink (it's seriously tiny) it's doing 3.4 on stk volts benchmark stable, reported (belivable) 40c load temp.

Still pushing it though, see when it falls over.

Wow, that cooler is tiny like the dual core Xeon HSFs. I bet if you put that massive Phenom II stock HSF on there it would make a big difference for overclocking. I see 4+Ghz on air prime stable with that HSF.

The Phenom I/Phenom II coolers are godly on 65-89W TDP CPUs.

This time when I am getting both a Athlon II x2 and Phenom II x2 I will even bother to try out the stock heatsink, something I've never done before:rofl:

Quick & dirty. Opteron 170 @ 2.8GHz on Win'7. 31.625s.

EDIT: 3GHz = 30.593s. As stated, it's quick & dirty. Thought I'd do it for those who didn't have the patiance for the "Extreme" users to do a proper job. :)

Me as similar nerd to you mAJORD can't wait for full review!

Don't forget to look at the memory timings/speed influence on performance! I have a feeling it might be quite important without L3 cache for some applications!

When you get bored with OCing try also some undervolting/underclocking of this chip. I really want to get it for my HTPC, because yesterday I found a matroska Hi-Def movie my 4450 stock have problem with ;)
05-31-2009, 06:00 AM
mAJORD

Hi Lightman :)

Certainly, I have that lined up.. I've completed an initial comparsion aimed at looking at difference between 6000+ and the 250 from a consumer pt of view. What I can't decide on though is NB frequency for an arcitectural comparison. With K8 there is no seperate NB clock domain. What frequency does it really run at? I've confirmed that despite NO L3 cache, performance does increase a small amount with NB overclocking. What is happening here?

These are the questions, So I'm not 100% sure on how to tackle that. :)

Anyway, I've Popped the lid on this beast.. so enjoy die size comparisons for now, and confirmation it is a brand new mask.

http://img46.imageshack.us/img46/3083/regorcomp.jpg

Brisbane: measured 8.5x 14.8 =125.8. Actual die size 126mm2

Regor: Measured 8.2x 13.5 = 110mm2.. Estimated..

So the 89mm2 was wrong. As I predicted! :p

Thanks for sharing !!
05-31-2009, 06:23 AM
Spectrobozo

the nb clock is the IMC clock, so I think it's expected to affect the performance.. in the k8 I think it runs on "full speed" same clock as the cores!?

Official release is the 2nd June here in Aus ... & just dual's for now ;)
05-31-2009, 06:28 AM
mAJORD

one would think so..

Perhaps the issue with high NB clocks on Deneb/Agena is related to the L3 itself, and the 2Ghz clock on this is to keep TDP's down, like with griffin, since performance delta is pretty insignificant over most benchmarks.

I have tried 2.9ghz clocks on this and they were fine at higher CPU-NB Voltage.. which may just be no higher than stock Vcore since by defauly NB voltage is significantly lower (on deneb)

Need the Datasheet for this CPU to confirm, as there's no indication in my Mobo's bios (voltage settings are an "offeset" from stock.. damn gigabyte)
05-31-2009, 06:46 AM
imamage

How high NB does this Athlon II x2 do ?
Can the L2 run at the same speed with the clock speed ??

I finally threw my Ph II 940 in my machine yesterday (replacing an Windsor X2 6000+) and on the DFI board the 1066 Ram setting defaulted to similar 5-7-7-24 2T timings. heh.

mAJORD, keep up the good work; do you happen to have any Windsor X2 6000+ results at 250 x 12, DDR800 or 300 x 10, DDR667? Or are you going to run all the comparison benches for the K8 fresh?

WOW :eek: you're brave mAJORD!
Popping lid in such a new CPU :D
Has it died on you or you were sure it will survive this operation?

When we can expect first results from you?
BTW in Athlons 64 mem controller was in sync with CPU clock, so X2 6000+ ran at 3GHz ;)

Independent IMC clock is required for independent core clocking. Also enabled K10 to maintain same memory frequency across a range of CPU multipliers (K8 memory speed varied depending on CPU multi.). Same as in Griffin, Regor will have ability to clock cores at different speeds. I only hope AMD added option to completely shut down a core when not needed! That would be cool on a laptop!

thanks Lightman..

The only CPU I'm not sure if it still works is the 9850BE, due to the heating process to flow solder, I bent the package, and failed to straighten it before it cooled (it was ****** hot!) and it's stayed bent. Have to try reheat+straighten and see if it hasn't fractured any of the bumps under the die!

I'll post results tonight, as an idea though, Agena/Kuma like perf. clk/clk Looking at around..
2.5-10% on basic integer varies wildly
10-15% for gaming/3dmark, (With a 2000NB)
POV ray in the 20%+
Encoding 10-15%

and an interesting one.. SSE2 Mandrelbot bench.. ~75%

most of the ~750M transistors go to the cache but not core.

Each core (with L1 + L2 cache) only consists less than 100M transistor.

Barcelona / Agena (4 core, ~4.5MB total cache): ~450M
Shanghai / Deneb (4 core, ~8.5MB total cache): ~750M

Fantastic work mAJORD! :up:

Now we can clearly see what K10 was an improvement compared to K8! All that was hidden under slow L3 cache and low clocks of the first Barcelonas.

BTW what os have you used for that comparison? 32bit or 64bit?

Also please do simulation of mobile parts with this core. First try to find lowest stable voltage @3GHz, then try the same @2.4GHz (reasonable clock for new mobile part from AMD) :)

Simply not true. PhenomMsrTweaker has always supported all K10 CPUs - you simply chose the wrong setup (64bit on a 32bit Windows, I guess). I don't even perform a check whether the CPU is supported... ;)

On the desktop It's aimed at the E5xxx aand 6xxx series.

it will also form the basis of the upcoming laptop platform though, replacing Griffin. It will be quite a leap from there, so should allow some decent competition.

My appologies. :( I messed up and did try to install x64 version accidently :shakes: the words CPU type not recognised instantly made me think it was the CPU, when you obviously mean no 64bit.. I'll report any problems with it shortly and PM whoever asked about it.

Anyway, UPDATE. initial undervolting results, as requested by Lightman:

Notes etc:

Power measured @ the wall. PSU is a 550w S12+ with PFC, so power readings should be reasonably accurate..

NO CPU reading taken as a reference, obviously it's not to be taken TOO seriously as the memory, chipset at the least will probably be in a lower power state with no CPU, but it at least gives a worst case idea.

Excellent work mAJORD! Fantastic! :clap:

Undervolting looks good to me, yields decent power savings.

P.S.
I forgive you about the PhenomMsrTweaker mix-up. :p:

Pretty amazing results! :eek:

It looks like at 3GHz 1.15V it fits nicely under 45W bracket and 2.4GHz 1V mobile part shouldn't be a problem for AMD at all!

Many thanks mAJORD for your hard work! :toast:

This is exactly what I wanted to see, now we have to wait for the price to fall:D

Very impressive. AMD gets some good yeilds and they might release some low powewr chips soon. Nice job.

So wat's the max speed that this cpu can achive?

so is anyone going to take on these to sub zero temps ?

prime candidate for a tec setup.

so far the highest i have gotten stable on mine is 3.82 with 1.47V.

However, with the rated max of 1.425 for the voltage i am going to try and stay within the envelope given which i am currently sitting at 3.75Ghz at 1.425 volts. Either way it was a nice little upgrade from my 7750 that was maxing out at 3.2.

Curious, anyone get any OC headroom with enabling ACC?

this is what i have going so far. this passed an hour of OCCT but i did not get in screenshot, my bad. Either way the chip seems to be doing well. I am having to run 1.49v though to get this high and my load temps on OCCT and Core Temp reach up to 35c or so after an hour. ill post more as i get em :D

There is a folder for OCCT (I think in my documents) that saves the screen shots of each voltage reading etc.

yeah but for some reason it errors out when saving to the documents folder or i would have it:shrug: i can reinstall it but perphaps W7 related? Not sure.

Regor is a nice chip, it was above my expectations tbh...

Review in swedish so take cover :p:

http://pici.se/pictures/KydGkGydq.png

My Regor was fully stable with volt decreased from 1.336 to 1.136. Overclocked to 3705mhz I had to use 1.424v, to reach higher I need to go beyond 1.5v+. I could easily do benches on 3800mhz+ but it wasn't stable...

yeah that is what I am finding as well. ~3.7 seems to be about as far as you can go at the 1.425v but beyond that does need a bump to keep stable. Great chip though i agree

Yeah, MSI 790FX-GD70, HD4850, 1 HDD, 1 DVD, 5 case fans powered with Corsair 650W.

I did stressing in LinX.

Cool, I just ordered a corsair 650tx to replace my enermax 400w. I'm looking to go to a 4870 and I wanted to make sure I'd have enough power overclocking.

Very good results Smartidiot89!
I like how Regor scaled on the same voltage with clocks! Power consumption barely changed :up:

It's a shame I can't get this CPU now :( I have speeding fine to pay :mad: (there goes my Regor - £60.00)
06-15-2009, 09:03 PM

temps in the low to mid 30's but this is what i have come up with so far. I have not had the chip but a couple of days but ill see if i can get a bit higher when i have time :D

With that PSU you can run a Quad-Core overclocked together with a Crossfire setup! :up:

Thanks alot mate that's my first attempt of making a "professional" review on par with most other HW-sites. We are getting a Portal on the forum soon so it will be alot more organized.

OT: The clocking surprised me too, both CPU's barely changed in fulload even if it was quite a decent clock. My best guess as far as Phenom II x2 550BE flying through the roof is cause it's a cut down Deneb.

Regor is a really nice chip which in my opinion is the best dual-core CPU in terms of price/performance/watt :up: And i love the fact that it stayed uber cool all the time no matter what kind of torture I gave it. Even with 1.55v my CPU cooler was still cold :P With my Quad-Core I could feel how the cooler had heated up abit even with stocksettings, and overclocked with 1.5v my case feelt abit warmish:D

Hello there
Reseller in Hong Kong just got Athlon II x2 in stock today

I got myself one piece (HKD$ 690 , $1 USD = $ 7.8HKD F.Y.I. ) and give it a little try
My friend plugged it in with a Biostar 780G mATX board and runs 3.73GHz @ 1.456V

This CPU runs cool too , I think it's ideal CPU to replaced my Athlon64x2 5050e in my ITX HTPC

i bet i can get higher but that was on an old Crosshair II (my M4A78T-E bit the dust) and i was running low on DICE

Dunno why
Only Vcore 1.5V allowed with my ASUS M3A79-T DELUXE after I plugged in this CPU
I can set higher Vcore with my 955BE ....weird

the 955BE defaults to a higher vcore you can set 1.5v in bios and up it further in windows with K10stat

This CPU is cool !!!
Undervolt it to 0.88V with Biostar 780G mATX board
with following hardware

Athlon II x2 250 @ 1.6GHz , NB 1.6GHz , Vcore 0.9V ( it shows 0.88V in CPU-Z) with Stock CPU Fan
1GB x2 Transcend DDR2-800
Seagate 160GB 7200.10
Pioneer DVD-116 SATA DVD Writer
with SPI 270W mATX PSU (Not 80PLUS , just a old PSU I got for my last HTPC)

CPU Temp almost the same as room temp , ideal chip
Idle only use 42W ~~ !

Nice chip you got there AMD:up::up:

Here is my Athlon II x2 250 with Jetway HA08

*** Notice ***
Just ignore the Vcore , Detect Error
I only use 1.45V to reach this

yeah i was curious what it would take to get above 3.9 stable enough to benchmark. I am happy with my 3.87stable for daily use but i might have to try for more later :D

I just tested it more with a 780G board last weekend
Put this Athlon II x2 250 clocked at 800MHz @ 0.9V with NB 800MHz
with the system playing some recorded HDTV program (DXVA VMR9 Renderless with KMPlayer)
The whole platform only consume < 65W power
Nicely done AMD

I've a question:
Brisbane vs Regor
How does that play out? I have an HTPC with a brisbane running 2.8ghz and have a 240 Regor that I'm wondering of replacing it with (wondering if it's worth it or not b/c my power consumption is roughly 56W idle with the brisbane).
