The x86 architecture will live on with the introduction of SSE5 in 2009.

Yesterday, AMD announced its plans to help improve the performance of applications on the x86 architecture with the introduction of SSE5 instructions.

SSE5 is designed to help software developers to simplify code and improve efficiency by giving them even more capabilities to maximize the performance of applications. The instruction set is currently being made available but will not debut in a chipset until 2009 when AMD releases its "Bulldozer" core for the Fusion line of processors.

The key components of SSE5 include:
  • 3-Operand Instructions - A computing instruction is executed by applying a mathematical or logical function to operands, or inputs. By increasing the number of operands an x86 instruction can handle from 2 to 3, SSE5 enables the consolidation of multiple, simple instructions into a single, more effective instruction. The ability to execute 3-Operand Instructions is currently only possible on certain RISC architectures.

  • Fused Multiply Accumulate - The 3-Operand Instruction capability enables the creation of new instructions which efficiently execute complex calculations. The Fused Multiply Accumulate instruction combines multiplication and addition to enable iterative calculations with one instruction. The simplification of the code enables rapid execution for more realistic graphics shading, rapid photographic rendering, spatialized audio, complex vector mathematics and other performance-intense applications.
For those of you who are interested, you can get a copy of the SSE5 specification over at AMD's developer site. Go ahead and take a peak and let us know what you think about it in the comments section below or over in the forums.

what about Intel?

if one is buying a computer now, choose RD670 or X38?? (had my eye on q6600 for a while now, and i want to upgrade to a native Intel quad later, are LGA775 still used by then? )

Interesting.
Lets hope this is not another 3DNow!

x86? Why not x64?

Because x86 is the architecture. x64 is just 64 bit x86.
x86-x64

Now can people stop refering to x86 as 32 bit, it started out as 16 bit

The reason for it being called x86 is because of the 8086 being the first of the line then the 286 the 386 etc.

AMD hopes to increase the performance of future x86 based processors with the introduction of SSE5 on its "Bulldozer" line of CPU cores in 2009.

:)

That's great! Now my spreadsheets, word processing, web surfing, and IDE Editor will really fly. I can't wait to see what it will do for the n-tier programming and security analysis I do.


Sarcasm aside, does it seem like AMD has been in the habit of announcing things, while Intel just gets things done? I really worry about AMD providing good competition, especially since they seem to be distracted by their ATI acquisition.

hahaha, so true, i'm still laughing. honestly though, if you know what SSE even is, then you're going to know its not going to do anything amazing for computer and it certainly won't make me want to buy an AMD over an Intel...

Ah, my bad, just thought it was that due to how Vista has x86 and x64 editions, so I figured x86 meant 32bit only :p

You might as well assume x86 is 32 bit architecture only because x86-16 is yonks old and hasn't been updated in ages. Plus, no-one uses the thing.

and they only call it x64 beacause its easier then saying x86-64 :p
computer people are lazy :D

Good news. But now we have to wait for the rest of the world to figure out what SSE extensions are for.

lol, it makes no difference to the rest of us, it's about time they lauched a solid competitor to the c2d line...
