XFX Radeon RX 470 Graphics Card Overclocking

The XFX Radeon RX 470 4GB Black Edition graphics card is already factory overclocked, but that didn’t stop us from overclocking the card even further.

To do overclocking on the XFX Radeon RX 470 4GB Black Edition graphics card we used AMD WattMan that comes with the Crimson drivers. We managed to get a 4.5% overclock on the GPU and we maxed out the memory slider at 1800MHz. Going from 1750MHz to 1800MHz on the memory isn’t that big of an increase, but it is better than nothing. Most importantly we raised the power target to 50% and increased the temperature target from 65C to 73C.

This overclock meant that we were running at up to 1315 MHz at times on the core clock when boosting and the 4GB of GDDR5 memory was running at 1800 MHz (7200 MHz effective). Not the highest overclock in the world, but you have to keep in mind the reference cards boost speed is 1206MHz and we are more than 100MHz beyond that.

By overclocking the XFX Radeon RX 470 4GB Black Edition graphics card we were able to take the score of 4,769 points on 3DMark Fire Strike Extreme and raise it up to 5,230. This is a 461 point increase in our overall 3DMark score, which represents a performance gain of 9.7 percent. The AMD Radeon RX 480 8GB reference card (1266MHz core and 2000MHz memory) scored 5,263 points, so with a little overclocking luck this card will perform close to a Radeon RX 480!

The main reason for this performance gain isn’t so much due to the higher clock speeds, but rather the higher power limit for the RX 470. By raising the power limit the card can maintain it’s clock speed better and that is why there is such a dramatic performance increase seen. It should be noted that we saw about 30 Watts more power being consumed by the system with the video card overclocked and the temperatures did increase with the raised target temp.

Let’s wrap this review up!

    I would expect the upcoming custom RX 480 cards to start around $229 for 4GB and $279 for 8GB, based on the RX 470 prices. That also puts the 8GB card in line with custom GTX 1060 prices. Like your article said, AMD seems to have priced the reference RX 480 too low.

    As such, to suggest buying a card that we’re not likely to ever see available again (reference RX 480 for $199) seems off in some way, at least to me. I guess it just depends on the actual prices for those custom RX 480 cards.

      I do not disagree, but this is a hit against AMD. Nvidia’s 1060 is comparable to the RX 480 8gb and essentially is cheaper now. Places like Newegg have been out of stock and when I get my auto-notify email that they’re back, they’re already sold out again. The “other sellers” have marked them up into the $335 dollar range which is ridiculous! Those are the laws of supply and demand though. Due to lack of product availability, prices are up and sales will go down, especially when team green can compete in performance AND price. I’m disappointed.

        Agreed. I’ve been checking for 6 weeks, trying to get the right card to replace my GTX 750ti for casual gaming at 1080p 60Hz. All the while fighting the urge to spend $430+ for a GTX 1070, because it’s in stock and has great performance. So on Friday I bought the card in this article, because it was in stock, and at least had core clock and memory speeds close to the RX 480 with better cooling, for $20 more. I just couldn’t wait anymore, and they’re profiting from it.
