I have a quick question, yeah I know I should of looked but...
Do the apu's even have hyper transport anymore?
What do the 890fx and 990fx use in wattage?
I thought it was around 45w's.

Thank you haylui,Quote:

May be caused by the low memory speed or not yet finished tweaking of the core itself. I'm curious about the power consumption at the same clock in comparison to richland. Guess it can be abit higher on kaveri if their top model comes with an 3.7GHz baseclock at 95W, but that lower clockspeed may as well be an tradeoff to higher GPu clocks.
I was looking at the results of the Kaveri ES in geekbench and was wondering how it fares against Vishera.
This is my setup at the moment:

and these are the results:

I was mainly interested in single core performance, and in my opinion it does pretty good. Multicore scores are lower, naturally.
Memory score seems too low, on the other hand (any thoughts on this?). My guess is that the chip was tested with basic 1600 mhz ram.
I will retest with my 8350 running at 3.5 ghz and ram at 1600 to see how it fares.

On single thread it's a win. On multithread, if we remove AES and Dijkstra out of the picture, the Steamroller CU's fare close or better to the Piledriver CU's (keep in mind the lack of L3 cache).
From the memory point of view i'm not sure what to make of it.
I think if we overclock these to 4.6-4.8 it should result in a faster chip than current visheras at least in single-threaded loads.
Not bad, I say.
Thanks for your test. But I feel sorry that your test makes no sense, because the Kaveri platform is running with single channel memory, and pulling down the result too much. I think you could make more test by running your FX8350 with single channel memory, and activating 4 cores only.Quote:

I've managed to disable 4 cores (this bios is not friendly when it comes to that) and swapped out one memory module.

I could test at higher speed. Maybe kaveri benefits from ram speed more than vishera.
Actually it was only around 20 watts even maybe less now since that was around 790FX time.Quote:

Found a nice video of Kaveri BF4 demo:
http://www.youtube.com/watch?v=axyHkKn_e80
1920x1080 @medium 30-40fps vsync off (known numbers up to now)
1600x900 @medium 38-52fps vsync off
1280x720 @medium 55-60fps vsync on
1280x720 @high 30-35fps vsync off
1280x720 @ultra 25-30fps vsync off
That gpu should easily get a 40% OC (720 --> 1Ghz), do the math.
Its possible to reach 1600x900 high @30-35fps with some tweaks+gpu/mem OC
aaaah yaaah uuultra pleaase try...lol
i feel this igpu could definitely hit 1ghz OC clock. slap a decent cooler on it with some 2400mhz+ memory.
should see some demo leaks pretty soon! ;)
A couple of slides are now floating around showing 3.7 Ghz clock and 4.0 Ghz Turbo (max), so at stock settings it's looking like it will only be about 5% faster in single threaded applications (give or take depending on the nature of the code). It also is looking like there will only be a 15% increase in framerate (apart from mantle-enabled games). I'm sure that we'll see the following revisions with better clock speed, but the switch to bulk from SOI isn't treating them well this time around. The last thing to see is what sort of power consumption the newer cores have. We may not see a huge drop, but there may be some decrease (especially under load; idle is already quite good).
I don't believe that, for a few reasons.Quote:

There may be other explanations, but the point still stands that they aren't hitting the clocks they needed/wanted, and they did with Kabini and Temash. This shouldn't be new territory, so something went wrong, and it may involve the switch. Other suggested explanations are always welcome :).
the only intended clock speed I recall seeing was for FX being 4.0ghz 4.5ghz for Zamebezi chips.Quote:

The APU's do not have a Hyper Transport because they are not meant to ever communicate with other CPUs in another socket and they have built in PCI-E lanes so those are used instead to connect to other chipsets.Quote:

Could that be a new revision of Vishera?

Real or fake?

Anyhow, wasnt there supposed to be some kind of kaveri preview this month ?
More bad news.
AMD roadmap for 2015 server wise:
http://www.youtube.com/watch?feature...&v=4Tf0wStiSXc
http://img801.imageshack.us/img801/4095/lq0k.png
So, after SR 4 cores there are 4 cored excavators with GPU.
What this essentially means, AMD doesnt want to build any non igpu more than 4 cores dies.If there would be anything bigger planned it would be in servers.AMD always doubled usage of chips from server to dekstop using same masks.
What is more troubling ,is that even jaguar cores vanish in exchange for ARM ones.
It essentially means that from NOW to END of 2015 there will be no bigger CPU from AMD than 4 cores.God dammit.
funny that it's called freedom fabric yet it's bga lol. (seattle cpu)
Hey, Toronto APU becomes a SoC! So Kaveri replacement will be new socket again, for DDR4 and SoC?
Also, thanks for that youtube vid vario, very interesting
I think Yes and No.
Look at information: DDR3/4
This could be as in Phenom II times (Phenoms can DDR2 and DDR3 too). So Excavator in desktop could working with FM2+ and FM3 boards. FM2+ are DDR3 and FM3 could be DDR4 boards?
