Intel Larrabee Graphics Channel

Wednesday, April 2nd, 2008

Here I go again writing about Larrabee the graphical architecture from Intel. Intel have decided to create a graphical add on board channel. What this is I’m not quite sure yet but the technology is set to take on Nvidia and ATI.

What interested me at this stage, Intel will create a healthy amount of tools for the architecture, predominantly to arise an interest. I was also interested that Intel have decided to include OpenGL Compilers into the package. Correct me if I’m wrong but Nvidia have the strongest hold over OpenGL compared to ATIs Directx counter-part. So what is Intel doing here? Giving Nvidia more competition? I assume so.

I will be trying to keep you all updated on the technology and hopefully have a more technical specification for you all.

Phenom stepping to B3

Tuesday, April 1st, 2008

When AMD first released their Phenom quad core processors AMD had a TLB problem. The problem was based with the instruction where cache is asked to overwrite another memory location. Since the processor shared L3 Cache when two cores tried to access the same section of Cache memory the cores would race to access that memory location. Each core would then try and rewrite this new memory location causing the conflict.

Now that AMD have sorted their problem and increased clock speeds how do they compare to Intels processors? As we already know, AMD are well behind from where Intel’s research stands. Intel seem to be increasing the glab between the contenders.
Benchmark results have shown that using the Q9300 processor one of the lower end Intel processors still performs better than AMDs x4 9850 processor. I know what i’d prefer! If you dont then I’d consider getting a low end intel quad core and then when money is not an issue :S get the extreme quad version.

So I guess Intel are still leading and will always lead unless AMD come back with a new graphical architecture such as Larrabee cough.
