In all technology sectors, rapid and comprehensive developments can be made: retrospectively some ideas could be suboptimal, but that doesn’t mean that it is better to stop the progress. I don’t believe that Merced would be received quickly and painlessly in PCs, desktop and especially laptops...

Theoretically it would be appropriate to design a new ISA freed of constraints and limitations of the 70s and 80s (CISC, cumbersome instruction coding, few registers, in order, memory management and coherency, etc.), perhaps with an ‘explicit management’ of ILP (a la E.P.I.C.) I...

By now I checked with 4 AMD cards (HD 5770, 5830, 6670, 6850) that GPU usage was always zero with the OpenCL code path. But I tested each card in a different system (and with different data sets!), so I can't compare compression times with different GPU. A well equipped laboratory could conduct...

That's technically correct; but according to slide and info from http://www.investorvillage.com/smbd.asp?mb=476&mn=235391&pt=msg&mid=11638341 or http://www.geeks3d.com/20111217/winzip-16-5-will-support-opencl-for-ultra-fast-compression-and-decompression/ <<WinZip 16.5 is being optimized for AMD...

I don't think so, because... Yes, I tried a RAM Drive and I checkd absolute performance and relative speed up, with and without OpenCL, with different data sets: the results were the same (and GPU usage was always zero!). Perhaps with a faster CPU or slower mechanical hard drive we can run into...

It doesn't seem so: I tried different disks on the same system, also I tried to use two different disks at same time (source, destination) but compression times were the same (+/- 1s).

I fully agree, of course provided that it actually does good use of a modern GPU. Thankfully this seems very likely, since Anand showed GPU usage with AMD System Monitor during transcode in the OpenCL enhanced version of Handbrake.

Adobe requirements are laughable: the official list rules out "complete" Fermi GTX480, GT200 GTX280/260 or dual GPU GTX295/GTX590 but includes GTX470 (GTX465 or GTX560Ti 448 are banned!) and GT200b GTX285 (not GTX275)... I hope that this is only the result of oversights and omissions... Anyway...

That's technically correct; indeed it's theoretically possible that an APU can be faster than a discrete GPU with more compute power, thanks to on die links and other optimizations. What I'm pointing out is that, in WinZip 16.5 with OpenCL enabled, GPU usage is exactly zero, despite a...

I have the latest WHQL Catalyst 12.4, with "OpenCL 1.2 AMD-APP (923.1) FULL_PROFILE". GPU Caps Viewer 1.16.0 detects one "CL platform" (AMD APP) with two "CL devices": Cypress and CPU, of course in this order. It could be. If so, then I suspect that there would be maybe a systematic problem in...

I am afraid that I didn't understand your post. I exposed some observations about general purpose lossless compression with OpenCL, not video transcoding/encoding with auxiliary fixed pipelines.

In Trinity review, I found very interesting that the latest WinZip version was in the growing list of GPU accelerated consumer applications. I tried to verify the OpenCL speed up with a supported discrete video card (HD 5830 with Catalyst 12.4 WHQL): the compression time was indeed reduced...

I thank you. I read the eight pages from http://forum.giga-byte.co.uk (and post a question there) I think that it is impossible that all 4 DIMM (already checked one at a time) become faulty at the same time. However tomorrow a friend of mine will give access to his PC (Athlon II X4 640...

Yes, I've tried running a subset of my PC (CPU, motherboard, RAM, graphic card, PSU and keyboard) on the table. The problem was the same.

Hi, I thak you for answers. The PC worked flawlessly for about three months. The 1090T worked OK with initial BIOS (F1), then i upgraded first to F3 then to F4. I plugged correctly both EPS12V 4+4 pin and ATX 24pin. I replaced Modu87+ 600W with Corsair CX400. I also tried to plug only ATX 4...
