Today not only did the guys over at videocardz disclose information on the upcoming Radon RX 460, they've also posted up AMD slides with the same information on the RX 470. AMD h as acutally been comparing this card with the R9 270 and in this context the performance differences appear to be significant.

First of all lets have a quick look at the specifications. The AMD Radeon RX 470 features 32 compute units. Compared to the RX 480 this is 4 compute units less. In the case of the stream processors AMD equips the RX 470 with 2048 (2304 on the RX 480). Regarding the number of TMUs the Polaris 10 Pro based RX 470 features 128, while the RX 480 can rely on 144. the number of ROPs on both cards is identical and it's 32. In terms of clock speeds the RX 470 runs at 926 MHz base clock and 1206 MHz boost clock. These numbers are just a little bit lower than the 1120/1266MHz base/boost you get with the RX 480. So far it looks like there will only be a 4 GB version of the RX 470 and the only RX 400 series card with 8GB of VRAM will be the RX 480. What's again the same on the RX 470 and the RX 480 is the width of the memory interface, which is 256 Bit, while reference memory clocks on the RX 470 are 1650 MHz (2000 MHz on the RX 480). This accounts for 211 GB/s of memory bandwidth (256 GB/s for the RX 480). Last but not least there is the TDP, where AMD communicates 120 Watt (150 Watt with the RX 480).

Now that we're done with the specs let's see what AMD is telling us regarding performance. As we already mentioned they are comparing the RX 470 with the R9 270, while there selection of games contains Battlefield 4, Doom, Fallout 4, Hitman and Total War Warhammer. In Battlefield 4 the RX 470 outperforms the Radeon R9 270 by a factor of 1.5, in the case of Doom the factor is a massive 2.4, Fallout runs at 1.7 times higher frame rates, Hitman benefits by a factor of 2.2 and Total War Warhammer, like Doom, performs a whopping 2.4 times better.

Compared to the Radeon R9 270 the RX 470 is definitely an upgrade, but will it also be enough to handle to competition from NVIDIA?
