OpenCL platform means the implementation of OpenCL. For example, in your case, you are using AMD's OpenCL software implementation for x86 CPU, but it's running on an Intel CPU (an OpenCL device)....

I ran it on a GTX 460 and it seems to run fine, though not very fast :)

Do you plan to make a version using FP32 (but probably in a more accurate way, such as using two FP32 to represent one...

Personally I think the best bet for video encoding is still CPU based solutions. APU may help a little as the close integration between CPU and GPU allows more computation to be done on GPU (such as...

There are a lot video editing workloads can be done on GPU. Transition effects, text/picture overlays, special video effects, composition, transformation, etc. are all very suited for GPU. It's even...

What's interesting is, in the history of computing, it's almost always something "coming from below." Mini-computers replaced mainframes (although not totally), and workstations replaced...

This also depends on what software you use. Basically, GPU helps on video decoding acceleration. This doesn't sound exciting, but it's still important, as it enables one to edit directly on H.264...

I mean compared to a notebook computer (as this is about tablet vs PC, not tablet vs TV, and no, I still don't see any good "HTPC" solution yet). A large screen is obviously better, but it's not...

Of course it's related to web site designs, but viewing a web site designed with tablets in mind is, IMHO, much better than on a notebook.

Right now QCOM's market cap is a bit lower than INTC, although they are on comparable levels. If you consider their P/E ratio, I'd say that they are all too low. Heck, considering that TSM also has a...

The first Intel 4004 MPU was fabbed with 2-inch wafers, on a 10um process. Interestingly, 4004 is still among the smallest commercial MPU ever, with a die size of around 12mm^2.

If what you want to make is a vector computer CPU, then of course :) Unfortunately, vector CPU fell out of the spotlight even in the HPC market quite some time ago.

IIRC the first i740 (I'm not sure about later revisions) do not cache texture on local memory at all. All texturing access are directly from main memory, so it's very slow. Certainly it's better not...

If GT3e's memory is indeed Intel's custom eDRAM (which, 128MB seems to be a very reasonable estimate), then the question is how Intel's graphics driver going to manage this memory.

In the link, there's an integrated GPU test. Apparently it's ~25% faster in 3DMark Vintage, and 30% ~ 40% in 3DMark 11. It's also from 11% ~ 26% faster in four games they tested. Since it's just GT2,...

Considering a 8Gb DDR-3 DRAM chip can be as small as roughly 10mm x 12mm (including package), I think it's possible that the off-die DRAM is 512MB ~ 1GB or larger. That'd be considerable if they are...

It's still important to see whether a game produces smooth frames even when the measured time looks smooth.

Recording the frames is still valuable because you can actually see the frames to determine whether it's smooth or not.
