Crysis 3 is a meh, a tech demo and nothing really worth playing. Crytek wants to eliminate single player games and Crysis 3 shows that partially what are they transfering too.

FMA means fused multiply add. And basically speed up situations like: a = a*b+c. Of course, the rounding error is different (in Float) for FMA than when it's done as a = a*b, a = a + c.

AVX is something like SSE. Do you remember about these instructions that were supposed to speed up Internet browsing? SSE? Then how they added few other instructions and expanded register and called it SSE2? Well it's similar situation, it's a larger register that can do more per cycle.

Four jaguar netbook cores is about the same as a core i3 2100.

8 jaguar netbook cores? Do the math. It's 2011 again and the i5 2500 is born.

Ps4 will be obsolete by 2015 and that's when I'm upgrading my 2500k. Consoles are stuck with obsolete tech as soon as they're released.

The bottom line is that even tho the PS3 is pretty dated compared to what the PC offers as far as hardware, they still managed to make games look and play great. Just imagine where we would be today if more developers took the time to full optimize and utilize our current mid range hardware on the PC. I have no doubt the PS4 will look cutting edge even without having cutting edge hardware.

Arkham city runs perfectly fine maxed out in Dx9. I'm convinced that the DX11 is broken on it, it more than halves framerates with no visual difference as far as I could tell. And the Witcher 2 is only demanding with Ubersampling on which has the same effect as Arkham city's DX11. More than halves FPS with no noticeable visual difference.

Sure I agree that DX11 in batman and ubersampling are not worth the performance hit but that does not mean they are worthless. Just because you can't spot the difference does not mean others can't. Further more "perfectly fine" is rather subjective. You sure as hell don't get solid 60 FPS with one card in thous games even when running DX9/no ubersampling (aside from using a TITAN). You might feel that regular dips in to the ~40 is good enough other do not.

Again, that is nothing more than your opinion so stop trying to act as though its fact. I'm enjoying Crysis 3 immensely as I have enjoyed all of the Crysis games. If Crytek is eliminating SP games then they are eliminating me as a customer because I have no interest in MP...

It's quite obvious the guy is either trolling or incapable of reading the thread and instead just dumps sound bytes and FUD into threads featuring products he doesn't like. Don't let him get to you, it's not worth it.

As for the whole FMA and AVX thing you guys are getting it. If Jaguar can do multiply and add in one theoretical clock cycle, and Ivy Bridge with unoptimized code needs two and Jaguar running unoptimized code is the same speed, that means that Jaguar does it in half the clock cycles.

So, I'm going to give you the benefit of the doubt, Kand, and say that 8 Jaguar cores are the same as an Intel Quad running legacy code. Even with that happening, considering FMA and AVX (from my experience) can do things in half the operations causing a two times speed up, puts a Jaguar 8 core at 2ghz that would be equal to an Intel quad both running legacy code at twice as fast if the Jaguar is running optimized code. So really, if Jaguar is getting fed optimized code with optimal compiler setting, it's going to be about even to an 8 core Intel at respectable clock speeds running legacy (I.E. Windows) code.

I gave proof of my claims, not sure what the problem is.
