ATI Radeon HD 3870 System Requirements. The processor achieved a peak single-precision floating point performance of 1.06 TFLOPS, being the world's first single-PCB graphics product. Radeon HD 3870 X2 (codenamed R680) was released on January 28, 2008, featuring 2 RV670 cores with a maximum of 1 GiB GDDR3 SDRAM, targeting the enthusiast market and replacing the Radeon HD 2900 XT.

ThatвЂ™s 640 Stream Processors in total with a transistor count that has climbed past 1.3 billion. While SapphireвЂ™s first take on the X2 is a reference design, Asus has done something that is most unusual by producing an X2 with four DVI ports.The X2's GPUs are made using the same 55nm production process as the HD 3870, and they support DirectX 10.1 and Shader Model 4.1, and have 320 Stream Processors in each chip. Add a PCI Express 1.1 bridge chip, mix the whole lot together on a 263mm-long graphics card and - bingo - youвЂ™ve got the X2.Based on 206,657 user benchmarks for the ATI Radeon HD 3870 and the Intel HD 5500 (Mobile 0.95 GHz), we rank them both on effective speed and value for money against the best 666 GPUs.You wonвЂ™t be surprised to learn that the specification of the X2 bears an uncanny resemblance to a pair of HD 3870s while the appearance is very much like a 3870 with an extra couple of inches tacked on the length. Take two HD 3870 chips - reviewed here - and two batches of 512MB of GDDR 3 memory.

Ati Radeon Hd 3870 Drivers To Overclock

The odds are that youвЂ™re in the same boat, so if youвЂ™re considering an X2 and fancy a spot of overclocking then youвЂ™d better budget about ВЈ150 for a new, suitable power supply.Installing the X2 was an absolute doddle as the CrossFire element is permanently enabled so you plug in the card, install the drivers - beta in this case - and youвЂ™re good to go.We tested the Sapphire card on an Abit IP35 Pro with an Intel Core 2 Q6600 processor and 2GB of Corsair memory all running Windows Vista Ultimate Edition. Your reviewer has a fair few high-end power supplies kicking around, among the, three that have four six-pin connectors for all manner of SLI and CrossFire configurations but none has an eight-pin connector for the graphics. If you want to use the Overdrive part of the Catalyst drivers to overclock your X2 then you need to use an eight-pin feed. Just like the old HD 2900, thereвЂ™s one six-pin and one eight-pin connector, and while you can use a pair of six-pin PCI Express connectors this has a downside.

This too is a reasonable comparison as the GT delivers a fair proportion of the performance of its big brothers, but thatвЂ™s what happens when a review sample arrives at the weekend. The comparison isnвЂ™t completely fair as the PowerColors have 1GB of memory on each card instead of the usual 512MB but it's close enough to act as a useful test.On the Nvidia front, weвЂ™d have liked to use a GeForce 8800 GTX as it costs about the same as the X2 but once again we let the side down as we only had an 8800 GT on the shelf. These boys deliver the same performance as the HD 3870 although they consume far more power. What we did have, however, was a pair of PowerColor HD 2900 XT cards.

The problem is that the HD 2900 XT cards in CrossFire danced all over the X2 in a way that they simply couldnвЂ™t manage in 3DMark06. Thankfully, the 1.1 patch sorts out this glaring flaw. When we first played Crysis it didnвЂ™t support CrossFire, so a second AMD graphics card actually slowed things down. Add in AA, and CrossFire gives you a 60 per cent increase in performance, and when the resolution is increased to an astronomical 2048 x 1536 with AA the gain rises to 75 per cent.In the same tests, the GeForce 8800 GT models delivered performance that started the same as a single HD 2900 XT but as the workload increased it became clear that the X2 had the legs on the 8800 GT to the tune of 50 per cent which seems about right as the X2 costs 50 per cent more than an 8800 GT.When we tested the graphics cards in Crysis, the most noticeable point is that CrossFire works.

LetвЂ™s face it, thereвЂ™s no reason for the 2900s to be faster than the X2 and the figures show clearly that this is the case.
