Oh its only details, no biggy I guess.
Nobody here knows why that happened, is all speculation. It can be that nVidia underestimated the HD 4800 performance, or simply nVidia was miraculously able to increase yields and SP overnight to improve product performance and positioning...
Yes, that's the obvious conclusion, not because the chips were crippled by default, just as RV770 chips aren't crippled by default.
In the end, we all know that ATi cards are cheaper to manufacture, hence better profits, no matter how much nVidia charges for it's cards, is clearly evident that ATi is earning more money for each card sold than nVidia currently with it's GTX200 line, but if we talk about a total volume of cards sold that's a different story, nvidia cards are selling well.
Cheaper, sure, how much cheaper though? Again, once you start cutting margins on a lower priced part, you start bumping into variable costs that extend beyond differences in the GPU, ie everything else that goes into makng and selling a video card.
If variable costs are similar and one part sells for 2x as much, obviously the part that sells for 2x as much yields more profit. You don't even have to look at Nvidia parts to come to this conclusion, just look at 4850 and 4870. How much difference do you think there is in price. Between the GDDR5 and better stock cooler, do you really think both parts were equally profitable at $200 and $300 price points? Of course not.
I just stated that to prove that the GPU itself didn't got smaller enough, LGA775 is a totally different platform which must adhere to certain standards for broad compatability with reference and aftermarket coolers. The GPU itself is just 20% smaller, but the information specifically is a bit hard to find.
The GPU did shrink though, the size of the heatspreader doesn't mean anything, they might've kept a similar package size to minimize re-design costs or changes in cooler/PCB design.
I don't see a low end SKU based on the GT200 chip, so a little of help here please...
It should be obvious, you claimed ATI had a use for defective parts as lower-binned parts, but claimed Nvidia didn't. The GTX 260 proves that is false, and also shows Nvidia's "defective" GPU sells for as much as ATI's high-end "flawless" GPU.
HD 4870 512MB at 50%? LOLL, I haven't seen an HD 4870 being sold between $150.00 to $175.00 yet, while is true about the profits quickly evaporate, is a moot point because the ATi card still cheaper to manufacture, you can't compare and use the same ruler to both SKU's because is simply not possible. May be that can apply to the HD4870X2, but the money is not in the high end market, is in the midrange were the cards are sold between $75.00 and $150.00 and ATi is very competitive there, but the nVidia's image as having the fastest single GPU currently makes it look better.
PowerColor 4870 512MB $165 after MIR
Plenty of others there for $175 or less on Newegg. You keep claiming the 4870 is more profitable, the same as you and others have said since launch, except what you're saying simply hasn't been backed by financials or market share reports. This latest report simply confirms it, AMD's attempts to undercut Nvidia have neither increased their market share relative to Nvidia, nor has it returned them to profitability.
As for mid-range and profitability, of course that's where the majority of cards are sold, but that's not necessarily true about profits. Reality of it is, a single GPU sold at $600 might generate more profit than 10 low-end GPUs, again, because of variable costs that are rather inflexible eating into margins.
I'll give you a clear example. Last quarter, Nvidia still posted a profit, despite the claims of GT200 being unprofitable with a higher gross margin % than the previous quarter. How was this possible despite GT200's unprofitability? Simple, even though their GPU profits were down, their GPGPU profits and margins were way up. How? A single GT200-based Tesla or Quadro card sold for $2000 would make up for the profit lost from 3-4 GTX 280 due to lower margins from price cuts. Same GPU, clearly very different profit margins.
