i believe the term nvidia uses is enthusiast :D;)
Those 3dmark results suck badly. With my 2900pro overclocked to 874/1000, and a Q9450 at 3.6GHz, I score 14.5k in 3dmark06. Are you trying to tell me that a 4850 with a 4ghz yorkfield is only scoring ~500 points higher than I am? Because that really, really sucks.
ROFL, and the 4850 was supposed to be as fast/a little faster than a 9800GTX?
R300, haha... that kinda would mean you'd have the gpu performance crown...regardless of price period. From all hints it seems that Nvidia the one pulling a R300, two generations in a row with the 8800GTX and now GTX 280. What ati is pulling is more like a Ti4200, high end performance on a budget.
My overclock shouldn't matter. You seem to be forgetting, the 4850 is supposed to have 800 SPs, more than double that of the 2900, AND it has double the TMUs, as well as general improvements to the architecture. Pair that with the fact that it's got a 4ghz yorkfield behind it ... 15k is not impressive at all.
Now unless it will see massive gains from memory overclocking due to being memory bandwidth limited, then I really do not see this being such an amazing card.

I am not impressed by this FUD, if I understand the situation correctly. The R300 was more than just being cheap, for its relative performance. It was about destroying the current alternative from nVIDIA by miles, and also even being competitive with nVIDIA's next generation.
R7xx current competitor (at release) will be the GTX 2xx series, and not G80 / G92. Simplified... there is not chance in hell, that ATI can pull a R300 this time around, but nVIDIA may do exactly that, just like with G80. G80 A2 (GTX) and A3 (Ultra) can still give any card a run for its money, when resolution and settings are taken to (playable) extremes.
That said, damn, I hope I am wrong.. because ATI leading the GPU segment in terms of raw effective performance - I'll be the first to welcome that (I chose R9700 Pro over the GF TI 4600 ... and never looked back, it was even very competitive with NV3x series released many months after).
1. 1 flop is not equal to 1 flop. Flops are perhaps the most hard/useless way of measure since there is no defined standard. A cell can both be 200Gflop and 17gflop etc.
2. ATI dont have a 1Tflop chip. They have a theoretical 1 tflop chip. effective it will be alot less.
Also 280GTX got 240 SPs, 4870 got 160 before you apply marketing.
not bad not bad
even though 8800GT is still a great card regardless of what is coming out from either camp
i just don't see these making any difference in my machine hehehehe
ATI is doing a great job here keeping nvidia in touch as they are going to make them think twice about what pricing the'll charge :up: ...good for us i must say :D
It's so beautiful *tear*, they better have plenty of cards at launch. :up:
It looks like a PowerColor HD 4850 with a 3DMark score of 15,194. The test system consists of a X9650 @ 4000MHz, 2048MB RAM and Windows XP. From what I can find this 1000 GigaFLOPs card has the GPU clocks @ 625MHz and the memory @ 1000MHz. If I'm reading this correctly isn't this test done at 670MHz/1100MHz?
HD 4870 does not have 160SPs. It has 800, just like R600 has 320. They are just different than nVidia's; for one they are clocked much lower.
If HD 3870 has 64SPs, then why do those 64SPs @ 775MHz outperform the 9600GT's 64SPs @ 1.625GHz by a huge margin?
Anyway, people are worrying way too much about 3D Mark 06. 3D Mark 06 is useless, haven't we learned that from G80 vs R600? IMO nobody should be benching cards on '06 anymore; it is 99% CPU dependent on just my 8800GTS 512MB, much less a RV770 / GT200 card.
Vantage is what matters, and of course games matter much more as well. In Vantage Extreme, HD 4850 scores ~2600 IIRC, meanwhile GTX 260 scores 3750~, so the GTX 260 is maybe 45% faster than the 4850. And that is at over twice the price. HD 4850 CF outperforms GTX 280 by ~100 points or so in Extreme as well. Given that HD 4870 should be ~30% faster than the 4850 that would put the GTX 260 only ~10% ahead of it in Vantage. Even GTX 280 would only be ~45-50% faster than it. That means that HD 4870 X2 will blow the 280 away.
whats that supposed to mean, and an SP is not an SP it could be a stream processor like ati has that acts like a cell and is fully programmable or it could be a shader processor and be hard coded into a bios and not allow full functionality when compared to a stream
and were do u get 160, if it has 480 were its speculated and this bench would forecast it to, thats 1/3rd and that makes no since, or 800 thats 1/5th that also makes no since
and on benching vantage is a BS bench its not using full dx10 its using the dx10 base so its really anti ati
Does the 4870 really have that many? I thought, they had a 1:5 ratio, in term of their FUD about SP count? R600 had 320 SP / 5 = 64 SP vs G80 GTX/Ultra that had 256 SP / 2 = 128 SP :confused:
I thought, the 4850 / 4870 only really had 96, increased from 64, but still with more execution units per SP than nVIDIA ... 1:5 vs 1:2.
In terms of execution units ... GTX 280 and 4870 is the same: 480(1:2) vs 480(1:5). Meaning 240 SP for nvidia and 96 for ATI, and there is the clock difference.
I thought, ATI's 320 SP for R600 was FUD and not the same as nVIDIA's 128 SP, which has two execution units (and counted as ATI does, that would be 256 SP).
Please someone explain.
Yeah, with a Q9450 at 3.6GHz and my 2900Pro at 874/1000, I score 14.5K in 3DMark06. The 2900Pro has 320SPs and 16TMUs.
The 4850 is paired with a QX6850 at 4.0GHz, and the 4850 has clock speeds of 670/1100, and it has 800 SPs and 32 TMUs. It's score is not impressive.
