Comment Vector Unit VMX128!=VMX (Score 1) 155

VMX128 on the Xenon PPC's is brand new and borrows from the design of the SPU's on the Cell these 2 chips are like brothers, they share more than just the same PPC origin they both feature this new type of 128register X 128bit SIMD feature. It's called VMX128 on the Xenon and the basis of the SPU's execution unit on the Cell.

Read down and yes i am not the only person to notice - the author of this article notices the coincidences about the VMX and the Cell SPU's.
Anyone who programmes the Xenon's VMX128 will be plesantly supprised with the Cell SPU's similarity. It's like having 7 or 8 decoupled super VMX128 units instead of just one locally coupled one. !

Note that the PPC on the cell only has VMX. But how odd that Xenon is the only PPC with "VMX128". Where did VMX128 come from all of a sudden and it just so happens to be great for multimedia and gaming ?. No supprise here VMX128 is a cut and paste subset of the SPU functionallity from on the Cell. Sure a full SPU operates decoupled from the PPC which allows 1 PPC to mediate 7 or 8 SPU's and it's local VMX while the Xenon's VMX128 replaces the traditional VMX. VMX128 is a cut and paste of the Cell SPU's.

Only two processors in existance have SIMD with a 128register 128bitdesign with multimedia and gaming enhancements they are the X360's Xenon and the PS3's Cell. Need i say more !

You obviously have no idea that Xenon chips PPC's have a completly new VMX128 register set and instructions which is a cut and paste of the SPU's of the Cell. The PPC core is not new at all it's the new VMX128 and the SPU's producing the big gains which allow the Cell to do 175+Mflops or the xenon to do 75Mflops. The VMX128 on the Xenon PPC's is a cut and paste subset of the SPU's design from the Cell!.

Slashdot users read and learn because anyone who fails to understand the following is uninformed >

The SPU's on the Cell and the PPC Altivec unit on the Xenon(X360) are very closely associated never before has IBM done a 128register 128Bit Altivec unit. The 128bit X 128register Altivec VMX128 unit on the Xenon is the best of any CPU it is also an almost perfect subset or cut down version of the Cell's SPU !.

In non braching calculations and assuming no cache misses VMX128 performance is equal to the SPU's performance this is not a coincidence it's a newly shared design feature in both the instruction sets and silicon fab and clearly shows the CPU designers shared alot.

The older VMX is only 32 registers. Only the Xenon PPC cores and Cell's SPU's have this new VMX128 type arrangement with 128 SIMD registers - especially enhanced for multimedia and gaming.

Yes correct the LHC will never work (in our dimesnion) - the story is not a story it's absolutley correct we can only ever continue to exist in the remaining dimensions where the LHC Fails. This is in much the same manner as we can only exist in a universe and on a planet which can evolve complex life like humans. I think it will gradually come to realisation on the LHC operators that their machine destroys every possible dimesnion in which it operates correctly - this discovery alone is worth the cost of the machine in some ways.
