This amazing!!! How does the Hypermemory 512 compare to their relative NVidia counterpart?

The Hypermemory 512 means that there's 256MB of discrete GDDR3 memory and then an additional 256MB can be pulled from system memory. That 256MB of shared memory would likely perform similarly to whatever nVidia has (can't remember their terminology... Turbomemory? :-) that's shared.

Beyond that, I haven't yet seen a benchmark comparison that provides specifics...

There realy is not a direct counterpart on Nvidia's side yet, eventualy there should be a Geforce 7600 Go, Right now the X1600 is a 17 watt part that offers performance as good or better than the 35 watt 6800 go (non ultra) or 35 watt 7800 go (non GTX) in newer games like Fear and Splinter Cell CT, Because of it's 12 Pixel shading pipelines. but performs considerably worse in older games like UT2004 where it's 4 TMU's and 4 ROP's cause it to be fill rate limited.

I thought nVidia has something called TurboCache. It's in all Sony notebooks...

Yeah, TurboCache is nvidia's Hypermemory equivalent, but I think Rastlin was referring to there not being an X1600 equivalent (i.e. GeForce 7600) yet.

That is what I was refering to yes, In some ways I expect the 7600 Go will be more well rounded with more TMU's and ROP's but if I were to guess lower pixel shader performance.

Turbocache is similar to Hypermemory, but Nvidia has for the most part only implemented on lower end parts as a substitue for physical ram, and then equiped the part with 16 or 32 megs of ram, usualy on a very small memory bus, I belive some TC parts are 32 bit memory interface. I also heard that Nvidia intends to sell cards with no physical memory using Turbocache in the future, we can only hope that is not true.

Ati has parts like the X1600 Mobility using Hyper memory. To augment their performance slightly. And their normal lower end parts like the X300 geting a bit more of a boost in performance. And AFAIK have not designed any super crippled 32 bit memory interface parts that use Hypermemory for life support.
