And its frequencies are in between those of the 2600 PRO and the 2600 XT. Everything is the same: architecture (120 streaming processors, 128-bit bus), similar design. The latter card is essentially the RADEON 2600 PRO/XT. All our contenders today are based on AMD (ATI) RADEON GPUs.Īt the same time, our readers will get to know not only production-line HD 3850/3870 cards, but also the HD 3650. So, this time we are going to review three Mid-End graphics cards of the $100-$180 price range and a more expensive HD 3870. When AMD introduced the RV670 based 38 products, they significantly undercut what NVIDIA had at the time… and outperformed those products at the price ranges they were introduced at.Like most people neither wear designer clothes nor live in villas, most users cannot afford expensive powerful graphics cards like GeForce 8800GTX or RADEON HD 3870 X2 and choose cheaper solutions instead. This is not to say that the RV670 is a bad chip at all, because it is actually quite impressive considering the heat produced and the power draw of the product compared to how it performs. Overall fillrate is affected by the 16/16 RBE/Tex units as compared to the G80 architecture which can have up to 24 ROPS and 32 Tex units (though their overall functionality is not exactly the same). That unfortunately has a significant impact on performance, as the latency involved with sending the data to the SPs from the RBEs makes for a very slow chip when compared to NVIDIA’s fast G80 based architecture. It does not use dedicated transistors to perform fast multi-sample color resolve, rather it utilizes the stream processors to do that work. While the chip is a math monster, it does have one large issue. A second DVI to VGA adapter might have been nice, but considering the prices on LCD monitors as is… it is probably wise that they forewent including one. The contents of the box are fairly minimal, but enough for most users. The chips also features UVD (universal video decoder) which can handle H.264 and VC-1 offloading with high quality post processing effects to improve video quality. It has some 666 million transistors (hopefully not a sign of the end times) which contain 16 RBEs (render back ends), 16 texture address/filtering units, and 320 stream processors divided into 4 large SIMD blocks.
The RV670 chip is a 55 nm product produced by TSMC. Going over the base specs at least one more time is not going to kill anyone, so a quick refresh on the RV670 and how it fits into the HD 3870 is in order. Later on we can examine what may be best for users contemplating one or the other product for purchase. The one major advantage that the 9600 GT does have though is price. While the overall performance in many games for this new part is very competitive to the HD 3870, there are a few wrinkles where the HD 3870 excels. The one big monkey wrench for AMD’s highest end single graphics chip card is the newly released NVIDIA GeForce 9600 GT. The card is not overly well protected, but it certainly arrived without any issues or damage. Today I am looking at the big brother of the 3850, and VisionTek has done a few things to differentiate it from other boards based on the reference design. In it I had explored the past of VisionTek, as well as taking a good look at the technology behind the RV670 chip and what it brings to the market.
Previously I have reviewed the VisionTek HD 3850, which is the more budget oriented RV670 based part from VisionTek. VT HD 3870 Introduction Previously we have reviewed the VisionTek Radeon HD 3850 card, but how does its bigger brother compare to the competition from big(ger) green? VisionTek has been making a pretty significant push into the retail market as of late, and the HD 3870 is their mainstream offering in the $169 to $200 price range.
