AFAICS, ESRAM doesn't mean "embedded SRAM"; it's a specific type of SRAM designed by Enhanced Memory. Microsoft aparently licenced the IP from them? "Embedded SRAM" wouldn't make much sense really, when is the last time you saw non-embedded SRAM? (OK, I remember those separate cache chips...

It doesn't lose steam, it's twiddling thumbs. You're looking at it from the wrong end. ;)

It's funny how it's always been useful, for a useless synthetic benchmark. I've found it a useful ballpark figure of a given product's performance, for 10 years. Silly score contests aside. There must be something in the wrong that they accidentally did right. :P

FINALLY!!! Yeh, it probably won't last. They'll clutter the layout to all hell like IE8.

Freely ignore this tangent, but I can't help remembering when "beginner's questions" were all about texel fillrates and driver problems. Looking at this thread for example... maybe we need a Dropout's Questions subforum. ;) Okay, kumayu, just consider this a free bump. (Well, for the good...

If you mean Apple's Macs, OS X has lots of FreeBSD in it, but not Linux. Agreed, turning the IrisGL library into the OpenGL open specification was definitely a massive Good Thing, but what overlooked pieces do you mean?

Late reply, but just curious, was Fire GL then yet bought by ATI or was it the original (German?) company? I can't tell from the pic. I remember seeing some benches where they bested even the mighty Wildcats in some professional apps. Sure is a purty mofo you have there!

Me too has seen leaked pics of prototypes and mock-ups and last minute cancels floating around. I guess better believe a product when it's properly in the retail channel. *cough* Voodoo5 6000 *cough* Well, that can actually be perfectly all right if you have good (lots of big slow) case fans...

Unfortunately, this is complete bullshit. Because you are ignoring the fact that 24 fps film imagery is built of frames with the inevitable motion blur from the non-zero camera shutter speed. Computer game imagery is perfectly, absolutely crisp and therefore does not blend in the viewer's...

Strange... This: "The IBM PowerPC 750CL RISC microprocessor is a 32-bit implementation of the IBM PowerPC family" doesn't quite compute with this: "Finally, the chip is powered by one floating-point and two fixed-point units, which are capable of both single and double precision...

Come on people, it's in the SGX, somebody must know something... or could Simon F help out here?

Well, no and no. 64-bit addressing allows for a larger memory but that's irrelevant here. It doesn't increase memory efficiency as such. As to performance, 64-bit operands consume more cache space and bandwidth; while having them doesn't do much anything for performance. (Unless you really need...

I'm interested in the architecture of PowerVR's unified scalable shader engine. Does it have vector or scalar units? Does the thread management derive from their Metagence stuff, and does that imply anything interesting? How scalable is it, can you combine much more than 8 of them for a...

Dave, what can you tell about the Thor geometry/master chip for the original* DX6 Glaze3D? There were hints at checkerboard-style tiled load-balancing (for two or fours rasteriser chips), but not much beyond that. How far was it designed -- did it even reach the drawing board or was it just a...

There's already several threads about it on other sites too. Please use those instead. :-P Seriously now, this thread (the Famitsu article) had the interesting bit about Nvidia's coop with Havok. I wonder if the new situation means or leads to any increasing cozyness between Nvidia and Intel...
