First AMD HD4870 Review Out: Beats GTX 260

Say hello to the Radeon HD 4850 and Radeon HD 4870. We think you will be pleasantly surprised with the real-world gaming experiences we are having with AMD’s new GPUs. We evaluate the Sapphire Radeon HD 4870 and VisionTek Radeon HD 4850.

Single HD4870 beats GTX 280?

You can almost hear the fanboys vibrating with excitement over the Radeon HD 4800 series. The buzz has been building for weeks. For the first time in quite a while, AMD would seem to have an unequivocal winner on its hands. Read on for our in-depth take on this impressive new GPU.

I think all GPU manufacturers skipped GDDR4. But yeah, AMD's chip is ocmpatible GDDR3 and 5, like the GTX series from nVidia, iirc.

I think the listing was incorrect

I think manufacturers are able to choose between GDDR3, GDDR4 and GDDR5

Seen a first-price 4870 on the web at 219€, and it is mentioned as having GDDR3.

Given the level of excitement the HD 4850 left, not only with us, but also gamers and enthusiasts all over the world, the HD 4870 quickly became extremely anticipated by people. Will it beat the GTX 260? - How much faster than the HD 4850 is it? - Can it out-perform the GTX 280? - How does Crossfire scale?

These are all questions that we want answered, and today we intend to have answers for all of them. On paper the HD 4870 looks to be the right card for a lot of people. On the internet, looking at early prices it also seems to be the right one. Ultimately though, what it’s going to come down to is performance.

As for the new business, the Radeon HD 4870 is not only based on an efficient architecture (both in terms of performance per area and per watt), it is an excellent buy as well. Of course we have to put out the usual disclaimer of "it depends on the benchmark you care about," but in our testing we definitely saw this $300 part perform at the level of NVIDIA's $400 GT200 variant, the GTX 260. This fact clearly sets the 4870 in a performance class beyond its price.

uhm current HD4870 cards have 512Mb GDDR5

Even though I'm afraid of the quality and/or heaviness of AMD drivers, I think I'll make the 4870 mine as well.

On a sidenote, wouldn't it be better to wait for the GDDR5 cards? What would the pricetag be of those GDDR5 cards be anyways?

It has been a hard two years for ATI and we know that many people out there have been counting down the days until the boys in red returned to competitiveness. Well ladies and gents, the wait is over because the HD4870 has shown us that ATI has come out with all guns blazing. While the HD3870 and HD3850 were popular cards which have been able to compete on a number of fronts with their Nvidia counterparts, we are quickly coming to realize that they were nothing more than technology demonstrators for the 55nm manufacturing process. This process has now blossomed into full maturity with the R770-series cards which seem set to take the graphics card world by storm.

Last week, due to some unexpected circumstances, we were able to post a sneak peek of the RV770 GPU and ATI Radeon HD 4850 graphics card. As our limited testing showed, the Radeon HD 4850 was quite promising for a $199 graphics card. But we weren't able to tell the complete story. While the initial benchmarks definitely looked good, there was a lot more to talk about in regard to the Radeon HD 4850 and the RV770 GPU at the heart of the card.

Today we can finally spill the rest of the beans. You see, AMD didn't plan to officially announce just one new Radeon HD 4800 series card this week, but two, with a dash of information about a third thrown in for good measure. Today marks the official arrival of not only the Radeon HD 4850, but the higher-end Radeon HD 4870 as well. As we've already explained, one card - the Radeon HD 4850 - is targeted at the sub-$200 price point. The other, however, is a $299 screamer that makes use of some cutting edge technology, like GDDR5 memory. Come on by the site and check them out...

While the Radeon HD 4850 launched early last week due to boards slipping out into the retail channel, today is the true big day for AMD's next-generation graphics architecture, as the lid is lifted on their flagship Radeon HD 4870 part as well as the technology which powers the RV770 core utilised by these boards. To that end, in this article we delve into AMD's RV770 architecture, to see both what it offers over its predecessors and also how it marks a sea-change in the way AMD will be competing in the 3D graphics performance race from now on.

Starting out with the basics of the core being launched officially today, we find that RV770 follows AMD's previous RV670 part in using the latest 55 nanometre manufacturing process. While this part can't quite reach the billion transistor level sported by NVIDIA's GT200 core, it isn't all that far off, with a total transistor count of 956 million, against the 666 million transistors used by the Radeon HD 3800 series.

This increase in specification and transistors also sees die size increase over RV670 as you would expect, with RV770 clocking in at 260mm squared against the 190mm squared die of RV670. This still absolutely pales into comparison with the vast die size of NVIDIA's GT200, which weighs in at absolutely massive 576mm squared.

AMD has been through some rough times the last year. Not only have they lagged behind with their processors compared to Intel but they also have not been able to compete at the enthusiast level with their ATI graphics cards. It was therefore quite interesting to attend to their briefing in Malaga, Spain a few weeks ago where they presented their new HD 4000-GPU’s. For the first time in a year or so AMD had a briefing which was filled with confidence and which left at least me with a feeling that AMD was very optimistic with what they were presenting for us journalist.

The product they were presenting was of course the new HD 4000 series of GPU’s. In focus was the HD 4850 and the HD 4870 but we also got some information for the R700 which I expect will be called something like HD 4870X2. These are the GPU’s that AMD are hoping will strike a big blow to NVIDIA’s market share.

As an opener to our launch day coverage, we'll be taking a plunge into the RV770 and seeing what what is new, what has changed, what stays the same (quickie note: not much) and how it all fits together. We'll also check and see if we can actually achieve the theoretical numbers using a number of synthetic tests ... don't worry, the whole gaming enchilada will soon follow, we haven't lost our focus.

It is going to be my next card because of the excellent value for money it offers.

Wow. I'm sold.

HD4870 performs on par with GTX260.... but

http://www.madshrimps.be/vbulletin/f...l-229-a-45137/

€226 vs €399 pricetag!


sometimes it does this:



which is very nice...

other side of the medal:




summing things up:



on par with GTX260, ~10% slower than GTX280. Not bad at all, just look at that price!
