We are quite happy to see AMD pushing it's latest generation technology out across its entire product line. We're waiting to sort out some issues with HDCP and our latest test version of PowerDVD Ultra before confirming the support, but we know first hand that it works on the 4800 series and we see no reason that it wouldn't on the 4600 series. To make things better, both of them include the same 8-channel LPCM support for HDMI from the 4800 series. The 4650 will chop another $10 off the 4670's pricetag.ĪMD lists board power of the 46 at 59W and 48W respectively and obviously they're single slot (with no PCIe power required). We won't see performance on par with the 3870 in general, but the 4670 will do some damage in certain situations, especially if AA comes into play.ĪMD is also announcing (but we're not testing) the Radeon HD 4650 running at a meager 600MHz and using 500MHz DDR2 memory. Of these, antialiasing saw a major benefit, but we also see changes like increases in cache sizes, texturing power, and z/stencil ability. The RV730 XT is a derivative of the GPU in the 4800 series cards, and it carries over some of the benefits we saw inherent in the architecture changes.
Let's have a closer look at the 4670's specs:Ĭlock speeds are a bit lower and we've got much less memory bandwidth, but the hardware has some advantages.
Today's launch is pretty interesting because the 4670 has the same number of stream processors as the Radeon HD 3870 (320), which at the time of its launch was reasonably competitive in the $180 - $200 range. The Radeon HD 4670 is priced at $79, which in the past hasn't really gotten you a very good gaming experience regardless of who made the chip.
