When AMD released its Radeon HD 4870 and 4850 the price/performance advantage over NVIDIA at the time was so great that we wondered if it would extend to other GPUs based on the same architecture. Inevitably AMD would offer cost reduced versions of the 4800 series and today we’re seeing the first example of that; meet the RV730 XT, otherwise known as the Radeon HD 4670:
Gallery: AMD Launches the Radeon HD 4670
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. 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. Let’s have a closer look at the 4670’s specs:
|ATI Radeon HD 4870||ATI Radeon HD 4850||ATI Radeon HD 4670||ATI Radeon HD 4650||ATI Radeon HD 3870|
|Memory Clock||900MHz (3600MHz data rate) GDDR5||993MHz (1986MHz data rate) GDDR3||
1000MHz (2000MHz data rate) GDDR3
900MHz (1800MHz data rate) DDR3
|500MHz (1000MHz data rate) DDR2||1125MHz (2250MHz data rate) GDDR3|
|Memory Bus Width||256-bit||256-bit||128-bit||128-bit||256-bit|
|Frame Buffer||512MB||512MB||512MB GDDR3 or 1GB DDR3||512MB||512MB|
|Die Size||260 mm2||260 mm2||146 mm2||146 mm2||190 mm2|
|Manufacturing Process||TSMC 55nm||TSMC 55nm||TSMC 55nm||TSMC 55nm||TSMC 55nm|
|MSRP Price Point||$299||$199||$79||$69||$199|
|Current Street Price||$270||$170||$80||N/A||$110|
Clock speeds are a bit lower and we’ve got much less memory bandwidth, but the hardware has some advantages. 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. Of these, antialiasing saw a major benefit, but we also see changes like increases in cache sizes, texturing power, and z/stencil ability. 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.
AMD is also announcing (but we’re not testing) the Radeon HD 4650 running at a meager 600MHz and using 500MHz DDR2 memory. The 4650 will chop another $10 off the 4670’s pricetag.
AMD lists board power of the 4670 and 4650 at 59W and 48W respectively and obviously they’re single slot (with no PCIe power required). To make things better, both of them include the same 8-channel LPCM support for HDMI from the 4800 series. 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.
We are quite happy to see AMD pushing it’s latest generation technology out across its entire product line. It’s great to see new parts making their way into the market rather than a bunch of old cards with slight tweaks and new names. Of course, AMD is fighting back from a disadvantage, so they don’t have the luxury of relying on their previous generation hardware to trickle down the same way NVIDIA can. But we certainly hope that AMD continues to follow this sort of trend, as the past couple years have been very hard on the lower end of the spectrum with a huge lag between the introduction of a new architecture and its availability in the mainstream market.
Also of interest is the fact that AMD has added support in the RV730 for 900 MHz DDR3. The move away from GDDR3 toward the currently ramping up and dropping in price system memory solution is quite cool. Let’s take a look at that in a little more depth.
