You're forgetting some other Penryn improvements. Take a look at throughput and latency improvements to various SSEx operations, for instance. (Super-shuffle engine)

But in most apps, most of what Penryn brings will be higher speeds & lower power. Assuming AMD provides any pressure at all for the higher-speeds part...

In terms of a 2-socket comparison, one near-term boost for Clovertown (and Yorkfield) will be the transition from Blackford --> Stoakley. Much better snoop-filter & throughput up 25%... should give the spec_rate benchmarks and performance-related apps a nice boost.

That's not "up to 15% IPC gains" against C2D, it's 15% against K8.

Add to that keeping a tight lid on benchmarks when there was no reason to do so if they were good, the change in emphasis from performance to performance/watt, the Henri Richards resignation, low launch clockspeeds, the focus on Specfp_rate (which is really little more than a memory bandwidth bench), the rumors out of Computex, and the "simulated" benchmark scores.

Really, the writing has been on the wall for months, just like it was for the R600 and for many of the same reasons. The only thing keeping the hype alive were the AMD forum boosters and their relentless efforts to shout down anyone who pointed out inconvenient facts.

Excellent post . :up:

Shouldn't CPUZ show "HT Link" link instead of "Rated FSB" like usual AMD cpus? If the HT link is actually running at 200 instead of 1000+, this would be a huge bottleneck as Mad Man said.

Isn't it very convinient this info comes from the intel exclusive place(coolaler forums),and that it is coming only a day after Theo's post??It could be that Theo's results were in some way inflated(since the score is really hard to believe),but this avalanche of "poor K10 results" comes after he wrote this:

i was talking about this:
cpuz 1.41 should be barcelona compatible, if i can call it that.
so cpu-z should show bus speed as 200mhz, and HT link 1000mhz for stock system??

Should, don't know why it says FSB since AMD doesn't use a FSB. Should have the bus speed (the HTT, has been 200MHz on K8) and the HT link (1000MHz on K8). Tells me that CPU-Z still doesn't detect K10 properly.
Unless that is a fake screenshot, with an intel chip in there and things mspainted or something like that ;) :p:

Conspiracy theories? The results fit with AMD's OWN DOCUMENTS on K10 performance vs. K8. Why can't you accept that AMD knows how the K10 performs? :shrug:

Don't tell me you listened to the non-technical hype from Pat Patla and the now-fleeing Henri Richard?

If L2 disabled but L3 is enabled - this will change things from slideshow significantly.

Lmao.With all the NDAs around,somehow Sun's got leaked and spilled out the all hush hush about K10 performance and summed it up to poor "up to 15% IPC improvement":rolleyes:

Can you post anything positive about AMD,ever?

Oh sure , the magic 38 cycle latency L3 will come to the rescue.

Sorry , but only an idiot could believe any of the caches or execution units to be disabled when the chip performs +/- 10% of C2D.

Reality is this : the chip is perfectly fine, but it's "bugs" prevent it from scaling , that is reaching higher clockspeed while maintaining data integrity.In other words ; you're fine at 2GHz , but at 2.3GHz* due to speedpath problems you get silent data corruption or other nasty surprises.

* Example.

I have the same number from a Cray presentation ; 15% better IPC ( that is for HPC code , which K8/10 likes most ) + extra % due to higher clock ( didn't happen ).

Can you post something anything true about AMD , ever ?

Reality is this:
You, nor I, nor most people here know enough to say for certain how the chip is going to perform. We have conflicting benchmarks from different sources. Just wait until after Sept. 10th and then we'll know for sure.

And no reason to be calling people idiots :rolleyes: just gonna raise tempers and not do any good. Geeez why can't people be respectful enough of each other to refrain from name-calling.... :rolleyes:

L2 is still twice faster than memory.
Also it has some smart prefetch.

Is there any such test showing how much performance would degrade with L1 and L3 enabled for other chips that already on market?

And finally, why K10 having lots of improvments against K8 shows exactly same performance per core? Where is 15% over K8???

+1
I don't understand why ppl thinks that it must be faster then C2D/C2Q in non-bandwidth dependent aplications.

the performance can't be compared with the phenom. try to bench a k8 with memory 667 cas5 and then change it to 1066 cas5 like the demo system AMD is showing. even at the same speed it will be a huge performance difference.

looking and comparing the cpu-z from Coolaler to mine it is a fact that his sample is a dvt or early bird from oem. so it will be the chip that launches within a few days. All features are enabled, K10 is no INT miracle it will be as fast as core and no penryn is not faster then conroe, it's just when the program is affected by cache or not it will be faster clock/clock and the magic sse4. k10 will increase the gap on fpu and IO even more not to mention virtualization. How well it scales will be depending on the new stepping coming in oktober and you'll see how well it does when people get phenom es in there hands.

informal's information about the bios is correct, it is changing alot, systems with b0 had no CPU options in BIOS available except changing HT speed.

---

The chips aren't bugged??? it's the BIOS at worst. Or maybe this is K10 performing at its best lol

Actualy it is faster than K8 per core (if these tests are true).

Yeah the whole 3-8%.

Actually it is within 4% difference for me.

So why were folks being flamed for suggesting old boards would suck with new processors? So, why bother with all of the BS about Socket Continuity? Guys, you can't have it both ways. It's either great with old boards and it's all good or its only so so and a new board is needed anyway. Ibet a new board is needed.

Rumor! A guy in Germany told me one tester is running Penryn on an i865, I told him I'd believe it when I see it. Yet, I wouldn't touch that setup with AGP, SATA1 and all of yester-year's tech. In fact, I'm already wanting to upgrade my GA-965 DS3.

I doubt we can expect more in non-SSE2-vectorized aplications. As was said before it is only up to 15% IPC improvements.

Same here. :D

whatever is out in Nov-Dec and is the fastest, I'll buy. :)

not really. In Cinebench is exactly the same, what doesn't make any sense, keeping in mine K10 improvements.

Somehow the massive core improvements amount to a 3-4% increase against K8.:rolleyes:

Doesn't make any sense at all.

The purpose of such devices is to move the PC as we know it on the cellphone. Current cellphones are slowly going uphill into PC territory ; this will advance at a very rapid pace once system-on-a-chip devices appear next year.The whole point is to move x86 down , into cellphone territory and this is the purpose of Silverthorne early next year. ( Iphone 2 will use it according to rumours )

This is real and is happening now ; both Intel and AMD are preparing for the 2010-2012 generation , by that time , cell phones will be more powerfull than current PCs.Add 3D glasses to them and all my multimedia needs are satisfied.

The numbers are about 7% better per-core with the clockspeed normalized.
