Sapphire HD 7790 1GB GDDR5 DUAL-X OC Graphic Card Review

I haven’t been impressed with any graphic card for quite a while and I must say I am elated to have come by this model of HD 7790 graphic card from Sapphire.

The card retails at around RM 480. Do note that there are a few variants of Sapphire’s HD 7790 range. This one is the Dual-X variant with 1GB GDDR3 and dual fan cooler that’s quite silent.

The most striking feature about the card is the dual-fan heatsink. A sleek design with silver and black surface, a whole lot of lines with a modern touch.

The card comes pre-overclocked and out of curiosity, I did overclock it further and manage to get the core up to 1200Mhz. It doesn’t actually help much with performance; which is why I do not over clock graphics cards like how I used to.

Here’s the GPU-Z detail of the card.

Benchmark

There’s a change in the benchmark system. The 2 new benchmarks used at goldfries.com are Resident Evil 6 and Just Cause 2. All the benchmark titles have numbers!!!

Bear in mind that the card is pre-overclocked, so I will state OC to refer to what it is and OC+ to refer to the added overclock (Core at 1200Mhz)

AMD cards work with this software, so I decided to pit the HD 7790 against the Intel Core i5-2500K

Verdict

What I am most impressed about this graphic card is the combination of price, performance and cooling. It’s running under 100w and temperature hovers around 70c even when the fan is only going at 40% speed in a warm room.

Worth shelling out a wee bit more $$$ to get this one over the HD 7770 cards. You can’t go wrong with any of these HD 77×0 series cards anyway.
