New Carrizo Benchmarks

Seen these a few days ago but never got around to posting them. It is SiSoft so take these findings with a grain of salt. The thing that caught my eye was the iGPU performance.

Which is mind boggling impressive. A10-7850k tests for comparison.

R7 265 w/ 2GB GDDR5

  • 623.68 Mpix/s (1024 SP @ 1025 MHz)

According to SiSoft Carrizo has as much compute performance as a discrete R7 265 with half the shaders. From what I have heard Carrizo runs a custom flavor of GCN 1.2. Needless to say it's quite impressive as these numbers in turn would mean that Carrizo's iGPU compute performance is more than double that of the Iris Pro 5200 and A10-7850k.

So no dual graphics mode then?

I'm not insulting anyone; I'm just being condescending. There is a difference, you see...

Unfortunately Carrizo will only be in AIO's and mobile.

Nope there are two Carrizo one fro mobile and one for desktop.

Nope. Carrizo is a 45W laptop part. Carrizo-L is a 14-watt ultrabook part. No desktop variants.

Until well given SiSoft doesn't have Kaveri benches since the OpenCL 2.0 driver update, this isn't surprising. Having a 0-copy option fully implemented with no translation in the middle opens a lot of bandwidth. Can't wait to see how Intel HD 6000 compares.

Give me a source not speculation or a statement from AMD.

 

Sorry mixed things up.

it already is a statement from AMD. Lisa Su confirmed this at CES.

Also, here's the existing roadmap as described. Carrizo is laptop. Carrizo L is ultra book. http://wccftech.com/wp-content/uploads/2014/11/AMD-Carrizo-APU-Roadmap.jpg

Look again.

I editted the post with the updated AMD roadmap. Sorry, but Carrizo is not coming to desktop.

Also, quoting AMD is tech report on the matter. http://techreport.com/news/27652/amd-carrizo-will-face-off-with-broadwell-u-wont-land-in-desktops

So, not even a refresh of Carrizo for desktops? What's on the roadmap for desktops this year? Or is AMD going to stagnate until ZEN?

Waiting until Zen I think. The desktop market has been contracting for so long now it's hardly a surprise.

Word from AMD employee when asked at CES said there was no plans for a desktop variant. There's a lot of reasons as to why but the primary one being Carrizo is fab'd on a low power node. Which means Carrizo probably doesn't scale well above 3 GHz which would make it slower at 65w TDP than the 95w TDP Kaveri at 3.7 GHz.

 

Nope. Carrizo is a 45W 15-35w laptop part. Carrizo-L is a 14-watt 10-25w ultrabook part. No desktop variants.

Rumor is we might see a FT1 variant of Carrizo-L. Something to possibly upgrade existing AM1 platforms.

 

Until well given SiSoft doesn't have Kaveri benches since the OpenCL 2.0 driver update, this isn't surprising. Having a 0-copy option fully implemented with no translation in the middle opens a lot of bandwidth. Can't wait to see how Intel HD 6000 compares.

It will be interesting to see on Carrizo as well. Currently Sandra only supports OpenCL 1.x. So this is pure ALU performance gains.

We will find out more about Carrizo next month. I think a Kaveri refresh may be in the works for 2015.

Kaveri refresh is the most likely option, just like they did with richland.

They probably give the steamroller cores some tweaks and maybe put it on the 28nm SHP node.

And the major upgrade will be on the GPU side with all its bells and whistles.

 

And then pray for a AM3+ variant, so I can finally decide how to upgrade my old FX-8120

Take Kaveri, whack the GPU off it, glue another Kaveri with the GPU whacked off to it, clock it to 4.0Ghz and call it FX2, live until 2016. 

You're welcome, AMD. :D

Steamroller was roughly a 11% increase in IPC over Piledriver. So new FX chips based on Bdver2 wouldn't be all that impressive. If Excavator brings another 10%+ increase in IPC that would be the architecture for them to build new FX chips from. Tho the architecture was designed for low clocks and low power so no new FX chips until 2016.

11% increase, aye? That would be more of a jump than the 6% Intel got from Ivy Bridge to Haswell.

I'm guessing AMD pulled a driver move to make OpenCL 1.x run like 2.0 and just as well use some HSA stuff to have the CPU augment the calculations done by the GPU.
