The Kaveri Pre-Launch Thread (A10-7800 and A10-6800k @3,5 Ghz)

[parvadomus]

I can see HSA and MANTLE helping a lot on AMD's Kaveri APUs, giving AMD time to develop a better big core.
First, HSA will help with lot of parallelized things like video encoding, image processing, etc. and at the same time it could work as a dedicated physics co-processor for games (ofc they need to develop on SW side for this, but it should work better than physx).
With MANTLE, you can make games to use the APU's GPU as a co-processor for effects, for example using it for AA, shadows, etc. Helping another low end GPU to get better frame rates, and avoiding the traditional AFR problems.

About the CB score, it gained like 10% IPC, but that was without adding FPU resources, maybe for the CB workload BD/PD were doing already OK in terms of branch prediction/cache structures etc. That alone don't define IPC. In fact super PI and wprime showed that for other workloads the IPC can be about ~30%.

wow dice claims up to 45% perf boost from mantle

Doesn't work. Can you upload?

Kaveri tech day

AMD is claiming some pretty impressive results if you ask me. Ill wait for the anandtech review though.

 

[inf64]

Kaveri die shot:

IPC up to 20% better according to AMD :

wow dixe claims up to 45% perf boost from mantle

Thanks for the link, found this part fun:

Goes from like 8.5 fps avg to 30+ fps with mantle vs directX.

Thats a huge differnce.

AMD is losing the GPGPU compute battle too. GT3 Haswell has more GPGPU performance than any APU.

Yeah, that's impressive even for a cherry pick.

lol I still have the site cached in my browser!

I would hope so considering the cheapest GT3 part is mobile only and in the $340+ range.

$255, and that changes once Broadwell arrives.

 

[mikk]

The gaming gains over Haswell GT2 1200 Mhz are similar to Haswell GT3e I think. So we might look for a ~20% increase over A10-6800k but since these are marketing slides I better wait for upcoming reviews.

I get, and agree, with what you're saying, but the comparisons only apply to products of similar price points and markets. You can't state Intel's GPGPU performance is superior to AMD's when the product you provide as an example for the readers is pretty much mobile only, and not to mention costs more.

Again, while I agree with what you're saying, I don't feel it's an honest argument when you fail to include all of the details. Besides, Broadwell is to be mobile-only, and will have no effect on the desktop sector where Kaveri will also, along with mobile, be competing it.

interesting slides.....i think that the company that loses most in this "APU marathon" will be.....nvidia :biggrin:

I think that the point is that if AMD is trying to compensate having very weak x86 cores by using the iGPU as a coprocessor Intel can also do it and maintain it's lead because that already know how to do a powerful iGPU for GPGPU

 

[Sweepr]

Wondering what ''up to 20% IPC boost'' means, probably not the actual average clock per clock improvement - but enough to offset the ~10% lower clocks. They might actually match 2009 Phenom II MT IPC this time (perhaps).

 

[9enesis]

if AMD is trying to compensate having very weak x86 cores by using the iGPU as a coprocessor

not likely...that would be stupid tbh.

Is this your new crusade now that your last points were shot down overnight?

What happened to them supposedly giving up in mobile and concentrating on the dying desktop market?

And what about this?

That will be your last "concern" over inventory and the WSA being shot down as well I guess?

SiliconWars is on vacation until after the launch of Kaveri for once again attacking another member. Who will be joining him?

Okay, who was still claiming that Kaveri was going to be at TSMC? Own up!

[krumme]

Its just a bad process for performance at this time also comparing to tsmc that is bringing 2.5ghz kraits to the market. But looking at die size for kaveri it looks dense and its probably cheap. Gotta sell for 80usd for a quad core. Great for low and lower midrange consumer desktop and notebooks. The performance is where its needed. With mantle games its a little gamer machine.

 

[NTMBK]

"CrossFire XDMA" block in there. Looks like we might get Dual Graphics that actually works for once!
