More Deneb 45nm Benchmarks

[Yokozuna]

The person that posted the Deneb Super Pi scores on the Chinese forum a few weeks ago has posted some more Deneb benchmarks: Cinebench; 3DMark Vantage; Fritz Chess; Sandra; Winrar; & Everest. Unlike the Super Pi results, which showed Deneb performing about 12% better than Agena, these latest tests show basically no improvement over Agena, with some tests actually showing markedly lower performance.

The tests were conducted at 2.3GHz & 3.27GHz

Cinebench



By comparison, my Phenom 9850 @ 2.3GHz scores 2012 & 7330.

Fritz Chess



By comparison, my Phenom @ 2.3GHz scores 5462

3DMark Vantage



I don't use Vista, but looking up Phenom scores on Futuremark's site shows that the 3.27GHz Deneb CPU score is about equal to a 2.9GHz Agena score.

Winrar



The poster mentions something about a "bug" in his comments on this test.

Everest



Sandra



Strange results for the most part, to say the least.

seems like the mem controller is still unfinished, but damn the 3rd level cache is fast

[BrowncoatGR]

Interesting. Keep in mind this is a first revision chip so it most certainly is going o have bugs. I wouldn't expect too much from Deneb in terms of IPC though.

[Extelleron]

This is the first stepping out of the fab. I wouldn't be too concerned about it not performing well. Clearly there is a bug with the chip given the subpar memory performance.

[Rammsteiner]

lol, weird.

Prolly some bugs though, but the tester typed bug already before he started any bench as well. And also, did you do your tests with 1.8Ghz NB btw? Because Deneb will run 1.8Ghz NB but the Agena BE's run it at 2Ghz. Not much but it might matter.

[doompc]

Hornet331, fast!?
The L3 cache on the 9850 BE is way faster than that:

and this surprises you guys?!?!? this IS amd we are talking about, the only thing they do good is gpu's so eveyone holding their breath for a goodamd cpu may as well exhale now ( not trying to troll, but c'mon seriously)

that's nonsense. you're not trying to troll, but actually it's exactly what you're doing

ont: even if this batch has still bugs the scores are extremely low compared to current phenoms.
even though, it's pointless to bench such an early ES if bugs are causing these low performance...

WTF, get a clue.

deneb has 200% more cache, so i call this fast.

[Rammsteiner]

It's relatively fast yes. However if you see the RAM bandwith as well, I think there's an issue with the NB. A bit early to comment on it, thus far it seems to OC quite well though. I hope they get the little bugs/flaws fixed soon though.

I dont want another TLB fiasco, nor do I think AMD can actually afford to have that.

Looking at what a C2D can do those numbers are really

[PetNorth]

Looking at winrar and Everest numbers, TLB patch is applied.

My guess: due to it is a very early stepping, it suffers TLB bug too.

[Extelleron]

It's not fast at all, no matter how much cache is onboard. Agena's cache was already very slow. Nehalem has 8MB of L3 and its cache is a good 50% faster than the L3 of the 9850/9950, and that's for the slowest model (2.66GHz).

There is clearly something wrong with the NB of C0 Deneb. Normally there are going to be performance problems with the first revision of any chip.

QFT.



that is pointless benchmarking right there.

So was your method the same back when AMD was on top and Intel could not compete? Were we just saposed to say "Oh well, we can never expect a good CPU from Intel again because well, its just Intel".

Good thing your not trolling

Well, my guess it is just a rough engineering sample and there are bugs to squash and BIOS opts to do... the data is sketchy at best and probably should not be taken seriously -- at least I hope not.

But AMD would need to be utterly stupid to propagate the TLB bug into their shrink.... this is inconceivable.


EDIT: The more I look at the data, the more I am convinced that the early engineering revision simply needs some work either this is an early stepping and not what will launch or the BIOS still needs to be worked over to tweak up the IMC. I put no faith in these numbers.

Well -- I don't think you will find too many people here that will not admit that AMD had a rough couple of years and did not execute well, but AMD has been stellar in the past ... it is in the best interest of anyone who enjoys comuting as a hobby that AMD brings out a strong product this next round.

[bowman]

It's pretty obvious that they're not going to release a chip that's actually worse than the original. Unless they're doing a Prescott, although, I kinda doubt them to be that stupid.

Either it's due to the early chip, or maybe the BIOS/motherboard recognizes it as an early stepping Barcelona for some reason and applies the TLB patch?

Either way I sure hope this will be a sweet alternative to Nehalem, I probably won't buy it myself (never say never though) but every Shanghai sold will fund the development of Bulldozer.

[grimREEFER]

nehalem has 8 virtual cores, it's going to be tough to beat in any modern benchmark that is fully multithreaded.

[philbrown23]

guys I used to use amd even when they sucked for years, like I said I wasn't trying to troll, but let's face it, at this point in time gpu's are what they do best, and as long as they stick with the same cpu diagram (wich is essentially what they are doing to cut the cost of changing to new technology) they will continue to fail. Sure they have 45 nm but they just took a regular amd cpu and shoved a smaller die in it, but if the diagram wasn't working (enthusiast wise) before then it wont now. Sure intel just shrunk their dies but they did it on proven to work technology.

Except that the same very thing was said for ATI. No one is expecting a 4800 series here, but a solid 3800 would be nice, making enough improvements on the architecture to make things viable again. Sure, we could just ignore AMD and assume they are dead, but why? There isn't anything wrong with being interested in what AMD or even hoping that something might actually surprise us.

[Spawne32]

i wouldnt say "doomed", but they certainly havent had a shortage of horse crap products thats for sure lol

[largon]

Obviously this thread is worthless.
Pre-production glitches at play.

[Macadamia]

I think they already started to shrink Deneb before the TLB bug was made known, or fix. So it was technically done in late 07/very early 08.

Why don't someone disable it through the MSR paths?
