DirectX 12 improves performance on Phenom II by 250%?!

The truly strange data point here is the 3.5x performance increase that AMD’s ancient Phenom II X4 955 sees between its unplayable DirectX 11 performance and its passable DirectX 12 performance. This is a pretty neat observation in that it gives us some hope that DirectX 12 will improve the relative standing of older multicore CPUs like this almost seven-year-old chip.

As an owner of an ancient Phenom II X4, I like this news

Only with AMD cards since AMD didn't do any DX11 optimization.

Phenom II X6 here.. about to turn it in a streamlink host for couch gaming, so this is good news

Do we have tests with Nvidia cards showing only modest relative gains on weak CPUs?

Yes we do.

Unless it comes from Raja I am sure you would reject it.

The numbers in the test is also quite odd unless I am missing something. Fury X and 5960X numbers should be identical. Not to mention their async test with changed parameters.

 

[Nothingness]

Yes we do.

It would be nice to have the origin of your picture

Computerbase.de tested various CPUs on both a GTX 980 Ti and R9 Fury X

"Durchsnitt" is average FPS, "Wenigen drawcalls" is few drawcalls, "vielen drawcalls" are many drawcalls

Waiting for Carrizo results... Expecting a mayor humiliation from Phenom II results.

INB4, Phenom II is far better than current Carrizo.

 

[Burpo]

Good news.. Thank you

 

[Justinbaileyman]

Would like to see if scaling improves with 6 core myself,so 6 core results please..

 

[nismotigerwvu]

If so that would be brilliant. I might be able to put off upgrading my rig a little longer.

Don't be like that, Carrizo almost matches Kabini in overall IPC

Why are you reverse trolling him?lol

What he means is the missing multithreading support in AMD's DX11 drivers.

You can see it here:

The single long dark cyan bar is the driver.

In this presentation you can see, that there is only one driver consumer thread:

This gives me good incentive to upgrade my old i5-2400 to an i7-2600 on the cheap!

More threads, more fun!

 

[csbin]

Yes we do.

beta2 Performance optimization


pcper is Alpha Test D:

Why are you reverse trolling him?lol

Good thing is that he trolls me, but sadly is a sour truth. Carrizo on desktop ended to be a big nerf compared to Kaveri.

I am sure the final boost from DX12 is going to be very game dependent and hardware dependent. Ashes (RTS game with a lot of draw calls) on an old, slow cpu like the phenom, is undoubtedly the best case scenario for DX12. And even then, I still consider it more of a technical demo than a real game at this point.

So overall, I am sure we will see a benefit, but very rarely if ever this kind of boost in a variety of types of real world games. It will be interesting to see the benefit in gpu bound games, which are the vast majority of games still, at least until the new 14/16 nm dgpus come out.

Edit: but if DX12 results in a revival of RTS games, that would be great in and of itself. It is one of my favorite genres, but hardly any games are coming out these days. BTW, is there any kind of release date for Ashes? Seems like we have been in early beta forever.

GPU bottleneck?

 

[master_shake_]

that's good news for the 7 people still using the 955.

seriously though, amazing results.

 

[ShintaiDK]

GPU bottleneck?

Of course it is. What else would he do to try make FX look good?

Count that 10 lol, I still have 2 PII x4.
