AMD Radeon RX 470 and RX 460: latest information
Table of Contents
During the PC Gaming Show at E3 2016, AMD CEO Lisa Su gave a short presentation on the new Polaris generation AMD Radeon RX 470 and Radeon RX 460 graphics cards.Since then, we have learned much more and with all the relevant information you you can read our article.
Appearance and cooling system
Let’s start with the RX 470. It has three DisplayPort 1.3 / 1.4 HDR connectors and one HDMI. The card is built on a modification of the Polaris 10 chip, which we saw in the older RX 480. Additional 6-pin power supply. There is support for AMD FreeSync. The length is approximately 18-19 cm and the width is 10 cm.
Positioning and performance
Both cards are built on a 14nm FinFET process, which will allow them to be more energy efficient than previous generations. Also, the cards will benefit from the new GCN4.0 architecture.
The RX 470 is marketed as an excellent option for Full HD 60fps gaming.
And the RX 460, according to Lisa Su, is suitable for esports disciplines and other projects with low performance requirements.
Also this model will be perfect for use in gaming laptops.
To assess the position of these video cards in the line, we recommend looking at the naming scheme for new generation cards.

AMD also noted that the cards from partners in the RX 470 can also have 8 GB of GDDR5 video memory.
Tests
AMD Radeon RX 470
At the time of this writing, the video card has already been released and the first results of its testing in games have appeared. Here’s an example of a text review from Overclockers. We summarize the results and it turns out that the new model performs on average 10-15% slower than the RX 480 with 4 GB of video memory. It is clear that in higher resolutions and more complex scenes, the older model with 8 GB of memory will gain an advantage, but the RX 470 was created mainly for Full HD and can be played with a stretch at 2560 x 1440. Comparing with the previous generation models, it is located between the Radeon R9 380X and R9 390.
As for overclocking, the new product can be overclocked on the same cooling system to an average of 1350 MHz from the standard 1206 MHz boost. The memory is overclocked to 7600 MHz, but this does not greatly affect, since the bottleneck here is the performance of the chip. Such overclocking gave an increase of 5-15%, depending on games and graphics settings.
AMD Radeon RX 460
The RX 460 tests are already ready and we will familiarize you with them. For example, here is a link to a text review from IXBT. This 1920 x 1080 card with 4GB VRAM lags behind the NVIDIA GeForce GTX 950 by an average of 5% and beats the R7 370 by 4%. As for the comparison with other Pascal representatives, this card is ~ 40% behind the above-described RX 470. This card is not bad for Full HD resolution and it will run new items for a long time, but its performance is far from being enough for high settings. Basically, as it was positioned, this card does an excellent job with esports games and other not very demanding projects.
With overclocking, things are not good. The chip runs up to 1360 MHz, and the memory up to 7400 MHz. That gives only 2-3% increase in productivity.
Which processor will unlock AMD’s Radeon RX 470?
We have a good article on this topic, where we explain the relationship between processor and video card. In this article, we’ll just say our choice. In our opinion, Intel Core i3-6300 and above would be a good choice for this video card. AMD FX-8300 overclocked above 4 GHz will also be a good choice, but it most likely will not reveal the full potential of the video card and with it you will not have a headroom for the future.
Which processor will power the AMD Raden RX 460?
For the RX 460, an Intel Core i3-6100 level processor should work well. Among AMD, it will be AMD FX-8300 at over 4 GHz. In principle, you can take an Intel Core i3 from the Haswell generation, but the frequency should be at the level of i3-6100, for example, Intel Core i3-4170.
Prices and release dates
At the moment it is known that the approximate Raden RX 470 will cost $ 179 in the US, and the ruble price will be 15,999 rubles. On the Radeon RX 460, prices are $ 99 / $ 119 (8299 rubles / 10299 rubles) for respectively with 2 GB and 4 GB of memory on board.
The RX 470 has a release date of August 4 and the RX 460 on August 8.
