ATI Radeon HD 4850 Preview: AMD Delivers Performance for the Masses

Crysis
For Crysis, we used the Crysis Benchmark Tool available from Crymod. Rather than testing our own recorded demo, this time we went with the built-in GPU benchmark that does a flyby of the island level. Our test was run with all the settings except for shader quality on high. Shader quality was set to very high.
With less than 5% difference between the 9800 GTX and the 4850, the new card from AMD certainly holds its own. it still isn't really playable at 1080p or higher resolutions, and even 1680x1050 is a tall order, but the 9800 GTX is in the same boat. Playing at 1280x1024 or lower or dropping down the quality settings is recommended until you start to spend much more money.

This is a fantastic card, and if it really sells for around 150€ here in Europe, this is the way to go. Very impressive offering from AMD, I'm simply amazed!The 4870 will often outperfotm the latest nVidia card, I guess... Combined with the supposed refusal of Intel to grant nVidia rights for designing chipsets featuring QPI links, this may mean hard times for the guys in green. They were a little early announcing a war on so many fronts, as it seems. Honestly speaking, I was tired from their domination and insane prices anyway, so this is a very nice turning point.

I knew there was a reason why I've stuck with amd for the last few years, because I always get my money's worth. It must be painful to be an early owner of a 9800gtx right now considering the huge price drop.BikeDude - Friday, June 20, 2008 - link
Why do you have to stay with a particular brand? Are you not free to pick and choose the best deal when you need it?Those who bought the 9800GTX a couple of months ago have been able to get a lot of good quality gaming going while some of us have been waiting for the next great thing. Personally I have been waiting for a while now, I still have a 7800GTX! Was the waiting worth it? I doubt so.
That said, I would really welcome some insight into the driver quality of nVidia drivers vs ATI. nVidia has been disappointing for the past two years. Instability, features gone missing, anomalies introduced (like resetting the colour profile in Vista after login), etc...etc... At one point I was unable to play a DVD for more than 30 minutes before my computer froze. Downgraded the driver and all was fine again. Luckily nVidia fixed that in a later release, but come on... That one was bad, and there's nowhere I can file bug reports.

Would be great if someone can run Folding At Home on this card and publish the performance.The new NV client is smoking right now, and lots of us are pondering buying cards to fold on.

it gets way too hot for a single slot card dumping the hot air inside the PC. Should be better when some aftermarket cards come out. But why does it draw that much power when the chip is much smaller than Nvidia's?epsilonparadox - Thursday, June 19, 2008 - link
From the hints in the article, I would assume this is a very large chip that nullifies any benefits the smaller process would have provided. Plus AMD chose a single slot solution which probably isn't doing a good job of cooling the chip.fungmak - Thursday, June 19, 2008 - link
Well the power that is drawn is about the same as a 9800 GTX.However, the 4850 is rumoured to have 950 million trannies compared to the 750 million of the GTX. Also, the die size is rumoured to be around 275mm2 compared to 330 mm"2, so slightly higher density, though i would imagine this is offsite by the reduciton in power due to 55nm compared to 65nm. So all in all the power draw is actually not too bad.

956 million transistors on 55nm fabrication process ;)ImmortalZ - Thursday, June 19, 2008 - link
The Multi-GPU pages seem to be broken - they go straight to the search page.derek85 - Thursday, June 19, 2008 - link
No the links are fine actually... Anandtech took this article offline for a very short moment for some reason and I hit the same problem during that time.
