Radeon HD 4870 X2: The Fastest Single Slot Graphics Card!

The guys at Rage3D have spent a lot of time to test the Radeon HD 4870 X2 with around 16 different games. The 4870 X2 is based on the the R700 GPU (actually two RV770). And their conclusion is clear: the Radeon HD 4870 X2 is the fastest card at this point in time. They also recommend, if you have the choice, to buy a Radeon HD 4870 X2 than two Radeon HD 4870 in Crossfire. And last point, an important advice is to have a fast, very fast CPU in order to fill the 4870X2’s command buffer (read send enough graphics data to the card).


Good things come in pairs


This test is focused on DirectX 10 and DirectX 9 titles and it’s a pity that Rage3D has not tested the 4870 X2 with OpenGL applications.

ATI Radeon HD 4870 1024Mb Review

This Radeon HD 4870 (RV770 GPU) with 1Gb GDDR5 of graphics memory can be seen as the answer to NVIDIA GeForce GTX 260 Core 216 (see here and here). And from the tests, the Radeon HD 4870 1Gb is a little faster than a regular GeForce GTX 260 Core 216 but has to compete fiercely with the pre-overcloked versions of the GTX 260 Core 216 (like BFG and eVGA).

Sapphire Radeon HD 4870 X2 Review

Technology doesn’t play favorites, and when it reaches an apex there is an indifference towards who develops it. ATI has learned this lesson the hard way, having watched from the sidelines for so long that most have forgotten that AMD could be a leader in technology. The Radeon HD 4870 X2 is the latest evolution in graphics cards, and ATI has delivered something bigger than we’ve ever seen before. Benchmark Reviews is fortunate to test the Sapphire Radeon HD 4870 X2 Dual-RV770 GPU video card 100251SR against a collection of todays hottest video cards available.

MSI Radeon HD 4850 Review

FiringSquad has reviewed the MSI’s Radeon HD 4850 that runs significantly cooler than ATI’s stock Radeon 4850 reference design. To reach that goal and offer maximum cooling performance, MSI uses four copper heatpipes for cooling the RV770 GPU. With their copper design, the heatpipes are capable pulling quite a bit of heat off the GPU. This heat must then be dispersed in order to prevent the heatpipes themselves from becoming a hotspot on the graphics card. To accomplish this, MSI employs a dual-slot aluminum heatsink.

Main features of the Radeon HD 4850:
– GPU: RV770
– 800 stream processors
– ROPs: 16
– Transistors: 956 million
– Memory: 512Mb GDDR3 256-bit
– core clock: 625MHz
– memory clock: 1.0GHz
– DirectX 10 / Shader Model 4.1
– OpenGL 2.1

The weird thing is FiringSqaud has used the Catalyst 7.7 to test this Radeon. Mistake???

Sapphire Radeon HD 4850 Video Card review

Sapphire has always offered the most influential ATI graphics products available, and the new Radeon HD 4850 is no different. Although it still uses GDDR3 clocked at 993 (1986 MHz DDR), unlike the 4870 version that is decked out with GDDR5, the Sapphire 100242L model offers 24x custom filter anti-aliasing (CFAA) on its 625 MHz 800-core RV770 GPU. Benchmark Reviews tests the Sapphire Radeon HD 4850 graphics card against the closest competition, and even compare CrossFireX performance in this performance review.
