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

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...

Nvidia reveals Specifications of GT300

A statement like "4xxx was out after the GT200 and slower" elides a number of key facts about the way the two GPU architectures match up, and does nothing to help consumers understand what the particular strengths and weaknesses of each company's offerings may be. In other words, this is a...

Nvidia reveals Specifications of GT300

Fair enough. As I indicated, I'm not an engineer, so it's hard for me to speculate why die sizes are what they are. In the context of the discussion to which I was responding, I think keys was suggesting that looking at performance/transistor merely in terms of GPU performance wasn't the...

Nvidia reveals Specifications of GT300

Oh, keys - and what I really meant to suggest by my first post is in the graph: the 4870x2, while having significantly more transistors, is only 30 mm² larger: 520 mm² compared to the GTX285's 490 mm². It's at a slight disadvantage to the GTX285 in terms of selling price/die size, but the...

Nvidia reveals Specifications of GT300

JL - As keys says, that's only looking at it one way: GPU performance. Would the GT200 die size be smaller without GPGPU stuff? Probably. The question is: are they getting enough extra GPGPU sales to justify the larger die size? We can't really know.

Nvidia reveals Specifications of GT300

Keys - I've no doubt that NV has other fish to fry besides gaming performance, and that's fine. The question would still remain, however, are they getting enough extra revenue out of the GPGPU approach relative to the increased costs associated with a larger die size? I couldn't answer that...

Nvidia reveals Specifications of GT300

Hmmm, I thought it was about producing a smaller, more cost-efficient die. So I'm not sure comparing transistor count in this particular case is particularly useful. Looking at total die size would be more useful, as would looking at the entire range of products which the R7xx spans, versus...

ATI Havok GPU physics apparently not as dead as we thought

Personally, I don't like the idea of the physics industry standard being in the hands of any major hardware player. Yet, it sounds to my un-technical ears that some want AMD to make a Faustian choice: either admit that they're refusing to implement PhysX out of spite (and lose hardware sales...

ATI Havok GPU physics apparently not as dead as we thought

Just a question, why would it make sense for AMD to adopt PhysX as a standard implementation, with PhysX in the hands of Nvidia? With a third-party in control of the implementation, they would have the incentive to make the implementation run as well as possible on all hardware. With one of...

ATI Havok GPU physics apparently not as dead as we thought

Whatever solution is implemented, there would be serious drawbacks for consumers (us) if it were not: a) hardware agnostic, and, b) vendor agnostic. By (b), I mean a solution that is not directly controlled by any of the principal hardware vendors. I.e., the solution has to be able to be run...

Even though the purpose of a business is to make a profit, that doesn't imply that it will never sell a product at a loss. It makes a great deal of sense to sell at a loss to prevent the erosion of market share, i.e. if the choice is selling at a loss or not making a sale, businesses will...

ATI partners don't want to reduce prices

Aren't there really two discussions here? The cost of the GPU itself, and the cost of the completed card? Both of which seem to involve enough factors to make detailed speculations dubious at best, and it seems likely that any arm-chair analysis of GT2xx costs is lacking. I'm sure that there...

Rollo is not making a fool of himself, it's just that his affiliation with NVIDIA means that he naturally wants to put the most positive spin possible on NVIDIA parts. Clearly the GTX260 has a few features that the HD4870 does not, and he's pointing that out. That said, one of those features...

9600GT SLi review

jared - I think that's true in order to come up with a reasonably-founded guess about performance, but why stop there? Why not just use RivaTuner to scale back SPs on an 8800GT and see what we come up with. The truth is, I've no idea how different the G80 architecture is from G92, on the low...

'Late to the party', 'already been proven', hardly. All respect to Keys and BFG--as I think it was wonderful for them to do the tests to begin with--I don't believe their tests to be conclusive in any way, which is indicated by the fact that both plan further tests. However, and this is the...

Look, we've done enough talking. There are some pretty straight-forward ways to test most of the 'theories' being floated around here. To sum up, there are a couple of fundamental questions to be answered: 1) Why does the 9600GT perform as closely as it does to the 8800GT given the...
