Are Richland desktops pre-ready?

[Sleepingforest]

Nope, SiliconWars said that Excavator based APU might get to 7850 level. Kaveri is ~7750 territory.

Oops, yeah, that's a misread on my part. When is Excavator expected?

Nobody knows(except AMD and that is not guaranteed lol) but my guess is not before H1 2015.

 

[Sleepingforest]

I can believe 7850 status by 2015. If they didn't at least meet that, I would feel pretty dissappointed in their ability to improve and innovate.

 

[Homeles]

I'd imagine you have no clue what Kaveri is? 512SPs with GDDR5 support. Why it wouldn't be on the level of 7750?

I made no comment on Kaveri's performance; I actually expect it to finally be an interesting mainstream desktop product from AMD. We'll finally get to see what all this HSA noise is about. Llano was poorly timed, and Trinity was mediocre... but Kaveri looks to be something worth keeping an eye on.

My point is that you seem to have been riding the AMD bandwagon lately; that is all.

I see that being almost entirely up to GloFo. And I definitely don't see 7850 level performance "by 2015" being reasonable, but I see "by the end of 2015" being possible.

Also, I don't believe this has been discussed on this forum yet: there are GDDR5m SODIMMs that have been outlined by JEDEC. So it's certainly possible that we'll see Kaveri run GDDR.

Homeless , I disagree . I can find more posts like those but you get the point.

A post back from September is not the best evidence of recent behavior.

 

[inf64]

Well that's when we found out what Haswell brings to the table . I don't have a problem acknowledging great innovations be it intel,amd,nvidia etc. I see others having that problem though .

 

[386user]

richland seems like a minor stopgap..

might hold off on haswell and wait to see what kaveri brings

I'm just saying you've been rather AMD happy as of late. CHADBOGA's attack was completely uncalled for, though.

It would help explain why AMD is moving into selling memory. It lets them make sure that at least one company (i.e. themselves) is selling GDDR5 SODIMMs to go with their APUs.

 

[lagokc]

There isn't any reason to believe Kaveri won't be near 7750 level performance, and there isn't much reason to believe that the Excavator APU won't be near 7850 level performance.

Let us hear the arguments against either happening - real arguments not "trololol its AMD they fail" that some people use every time.

A 7850 has 153.6GB/s of memory bandwidth. Unless Excavator has quad-channel DDR4 or GDDR5 then 7850 level performance is not going to happen.

7750 level performance is possible.

GDDR5 SODIMMs? Forget Kaveri, when can I buy a 2GB GPU that I can upgrade to 4GB later?

7750 level performance is probable with Kaveri. It won't be far off even with the slower GDDR5. Remember both the 7750 and 7850 are the salvage chips but still have the full bandwidth of the top chips in the segment, that is to say they both have more bandwidth than they realistically need.

If the Excavator APU is 20nm or below it will easily beat 7750 performance - AMD might target the 7790 instead of the 7850 though. I see no point in them releasing another chip if they can't reach 20nm after Steamroller.

As someone else has already said, the bandwidth is probably more than is needed for 7850, so if they use GDDR5, they might have the necessary bandwidth.

More the problem I see is TDP. After all, 7850 is over 100 watts I believe, and the cpu probably needs at least 50 watts. Granted a die shrink could lower the power usage, but if everything is on a smaller process in a couple of years, performance/watt should improve on low/mid level dgpus as well, so 7850 could be toward low end of the newest gen cards out then.

Even the 7770 and 7790 have 72 and 96GB/s memory bandwidth respectively. Even dual-channel GDDR5 at 6ghz would only give the AMD APU 48GB/s. If they went to triple or quad-channel they could get the memory bandwidth they need but they'd also drive up production costs.

So like I said, Excavator could get that type of performance but only if they really pushed hard for memory performance.

 

[inf64]

Don't forget stacked memory options.

 

[Phynaz]

Don't forget stacked memory options.

Don't forget AMD needs to sell these cheap.

 

[lagokc]

Well yeah, stacked memory would solve the problem but that's a few years off. By that time Intel might actually have a viable integrated GPU.

 

[Ajay]

Meh, Kaveri might make a good foundation for an HTPC (28nm). Richland isn't very interesting to me.

Maybe im wrong but im believe it works like this:

GDDR5 3400mhz: (believe FUDzilla mentioned this as the cheaper GDDR5)
128 x 0.850 / 8 x 4 = 54,5 GB/s.

With GDDR5 @ 6000mhz you would have:
128 x 1.500 / 8 x 4 = 96 GB/s.

This means that the APU's with the 512sp will come with 54,5 GB/s of memory bandwidth.
Which was also the rates that FUDzilla mentioned.

U must be European. At first I was, wtf? But they make sense now

 

[myocardia]

Thanks for the link! The only thing I recognize of those is Photoshop--how are the other applications useful in casual, everyday computing?

They aren't, and that's how you know their irrelevance.

 

[galego]

They must be mostly irrelevant for people who uses PC for reading email and updating status on some social net.

Some other people uses the PC for actual work.

 

[NTMBK]

-Photoshop
-Battlefield 3
-Final Cut Pro X
-GIMP
-Handbrake
-ImageMagick
-Mathematica 8
-Vegas Pro 11
-VLC
-WinZip

Either you're trolling, or you just know nothing about software... :\

About a year or so ago I think, I tried to make a list of programs that used OpenCL, via just googleing.
Im sure by now theres alot more programs that make use of OpenCL.

This is what I ended up with (havnt added to it in a longtime):

Your list is a fine example that proves my point. Cuda, OpenCL, DirectCompute, HSA etc. All hyped up beyond the sky. Reality is they are a tiny tiny tiny niche with extreme limited functionality due to their natural limitations. Even if they expanded 1000x they would not even account for 1%.
