How will SSE4 benefit games?

[math20]

Crysis will support SSE4 in a future patch and upcoming games will start to support it also, what type of performance gains should we expect to see with it enabled?

None of us know, at this point. With Crysis being a pretty GPU-dependent game, it likely won't help much. And of course, no processors besides Penryn's support SSE4, anyway.

crysis is both a GPU and CPU hungrey game...they both cause frame drops... While the FPS avrage might increase only a little, there should be less stuttering at cpu intensive areas...

As for the amount, only time will tell.

I thought that AMD's Phenom and Barcelona used SSE4-A / SSE4.1

Here's a link: Phenom CPU-Z

No. Both are not the same.

"AMD SSE4a

In the latest version of the programmer?s manual (for AMD64 architecture) of July 2007, AMD released a new instruction set - SSE4a. In the beginning we (YASM maililng list) weren?t sure whether this set is part of Intel?s SSE4.1 or SSE4.2 until a simple check of the documentation for CPUID shed some light and showed that there is a different bit for indicating the instruction set is SSE4a rather than SSE4.1. So now we got a new instruction set. What?s so special about it? Well nothing in particular. It only has a few instruction: extrq, insertq, movntsd, movntss."

Also, SSE4 had me worried, 'cause the main new feature penryn would have was that and I thought present core 2 processors would
loose support from future apps, especially games.

The reason for this fear was that some games refused to work on my PII due to lack of SSE support.
I was afraid this would happen with core 2 also. I was wrong.

The reason is given below.:sun:

"If I were to pick on Vantage for lacking a feature, it would be SSE4 support. I was given two reasons for it's lack of inclusion. First is development time. As mentioned earlier, development time is twice what was originally expected, so they couldn't afford to include SSE4 support if they wanted to. The main reason given though, is because that's a feature available on Intel processors only, and they didn't want to give Intel a big advantage for a feature not available on AMD processors."

I would not pick on Vantage! No, sir!

Now, if only Intel has support for this then I am sure most future apps and games would not make it a mandatory requirement.

Thank God for AMD not supporting this!

That's only because there aren't a lot of middleware solutions out yet to make SSE4 inclusion easier. Same issue that all the previous SSE standards had. It was only in the last 18 months or so that we started having games come out that required SSE2, which debuted with the P4 for Intel and Athlon 64 for AMD
