ATI Ships 2 Millionth DirectX 11th GPU; Update: Jan 11/2010, Fermi out March 2010

Neither of these two sentences add anything to the discussion.

ATI Ships 2 Millionth DirectX 11th GPU; Update: Jan 11/2010, Fermi out March 2010

I can't fathom what these two sentences contributed to the discussion. It's a company trying to score marketing points -- something that happens all the time -- why the bitterness? The situation with consoles is also hardly new. The console cycle will always slow down the pace of new...

5770 is NOT good as 4870 or GTX260

Yes he did. I just don't happen to think that we're all 100% precise with every statement we make when we're responding to a thread. I would guess that he was thinking of the difference in bandwidth between the two and misspoke. That happens pretty often in the back and forth of a...

5770 is NOT good as 4870 or GTX260

It really depends on your intent when you say "50% lower bandwidth." If you look at the above figures, you'll see that the 4870 has precisely 1.5x the bandwidth of the 5770, which is what I suspect AzN meant: (76.8 * 1.5 = 115.2) Now, as a function of the 4870's bandwidth, the 5770 has...

AMD on 58XX supply issues

IDC - Many thanks for the additional graph. Your explanations make a great deal of sense. While many of these issues are transparent to those in the industry, they are far more opaque to those of us who follow -- even with great interest -- from the sidelines. You've done a fine job...

AMD on 58XX supply issues

IDC - Looking at the curves for the last three process techs (65/55, 90/80, 0.13/0.11), it looks as if the revenue % (capacity growth), increases by a factor of 2x - 3x over quarters 4-6 of implementation. E.g., the revenue produced by at quarter 6 is roughly 2-3 times what it produced at...

GT300 Benchmarks

Ben, let me push back just a bit in one small way (and to be sure, I'm not one for the 'nvidia is doomed' perspective on all this). One place where I think the small-die strategy has helped AMD is in pricing flexibility. It has allowed them to effectively re-price previously high-end parts...

FPS Issues with 5870

I'm not much of a guru when it comes to troubleshooting problems like this, but I do recall hearing about the funky effects of using vsync. IIRC, you can get droped to a more easily managable fraction of the monitor's refresh rate. So if you can run a game at 120, it does just fine, until...

Nvidia kills GTX285, GTX275, GTX260, abandons the mid and high end market

We'll probably just have to wait and see what the availability/costs of these parts are over the upcoming months, and what the precise release frame for FERMI is. The problem with the EOL, as I see it, isn't so much that it abandons the high end; it's that it creates a mid-range gap between...

ATi 5850/5870 review thread

There is discourteous in delivery, and then there is discourteous in content. Discourteous in content is someone discussing the deceased's bad habits at the funeral. It is still discourteous and in poor taste no matter the manner in which the comments are delivered. Discourteous delivery...

ATi 5850/5870 review thread

Discussing a product's competitors in a launch thread makes sense. What doesn't make sense is beating a dead horse for nearly 30 pages. The reviews exist, and they include numbers from competing cards for comparison. The comparisons that go on here are largely invidious in nature, not...

Power supplies and video cards

I can't say that I'm an expert, but I'll repeat what I've found here and elsewhere: take a careful look at the rating of your 12v 'rail' (or rails) on the PSU. I've got an Antec TPII which is rated at 430W, but has two 12v rails, each delivering 17 Amps. At times you can combine the total of...

Nvidia reveals Specifications of GT300

Guys, I think this is all a mountain over a mole-hill. I simply think what Marc is trying to say is that he feels: 1) G80 wasn't initially designed with GPGPU in mind. 2) That, despite the close proximity of CUDA's launch to G80, the development cycle for G80 was long enough for it to...

Nvidia reveals Specifications of GT300

Keys - I don't find Marc's comments contradictory at all. He's simply saying that he doesn't think that NV designed G80/GT200 with GPGPU in mind, but that they knew they would make good GPGPUs from the outset because of the kind of chips they are: massively parallel. In fact, I can't tell what...
