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

Final Words
There's an unexpected amount of concluding we can do already based on these early results.
For starters, the Radeon HD 4850 looks to be the best buy at $199, even better than NVIDIA's price-dropped GeForce 9800 GTX. What's also unbelievable is that compared to the 4850, our beloved GeForce 8800 GT seems downright slow in a number of benchmarks - and the 8800 GT is only 8 months old. It's also very refreshing to see this sort of competitive pressure at such a reasonable price point, while it's fun to write about 1.4 billion transistor GPUs it's a dream come true to be able to write about this type of performance at under $200.
Take two 4850s, put them together and now you've got something even faster than NVIDIA's GeForce GTX 280 in most cases. It shouldn't be too surprising since 8800 GT SLI and 9800 GX2 both outperform the GTX 280 as well.
Our CrossFire investigation illustrated a very good point: AMD's multi-GPU solutions still don't behave as well as their single-GPU products, there are still cases where performance doesn't improve at all and that's where these large monolithic GPU designs hold their value. Hopefully with continued effort in the multi-GPU space AMD can get us to a point where there is no perceivable difference between single and multi-GPU solutions. Until then, NVIDIA's strategy will continue to have a great deal of merit - although the GTX 280 isn't the best example of that, at least from a gamer's perspective. On the CUDA side however...
We'll have much more information on the Radeon HD 4850 and its faster brother next week when we can completely unveil AMD's RV770, until then sit tight and be content with the knowledge that the days of the 8800 GT vs. 3870 weren't a fluke, the new mainstream wars are upon us thanks to AMD's Radeon HD 4850.

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.
