thumb1HIS HD 5870 iCooler V Turbo X 1GB

The name is quite a mouthful, but the card itself is one of the fastest on the market right now. With higher than standard clocks out of the box, the Turbo X aims for high frame rates indeed.


When the AMD ATI HD 5870 first appeared, it was instantly obvious that this card was something special. Many folks wanted one, but there was a little bit of a shortage of 5870's to go around, and this did slightly hinder the production of third party 5870 cards.

This is of course old news now, and many card manufacturers have released multiple versions of the 5870 to cater to different areas. Pre-overclocked cards are liked by many as they offer extra performance without the associated risk and as such you can find plenty of higher clocked 5870's out there.

One of the fastest is the new . This is a step up from the previous Turbo version, with the Turbo X offering a high 900MHz on the GPU and 1225MHz (4900) on the memory. A nice boost indeed, especially since many manufacturers so often don't increase memory speeds. Let's see what the higher clocks gets us shall we?

The box for the HIS HD 5870 iCooler V Turbo X sports the Call of Duty: Modern Warfare 2 design that HIS have adopted recently, and indicates that the game also comes with the card. The front of the box shows you some of the most important features of the card while the rear goes into more detail.

Inside the outer box we find a gray inner box. Inside here, the extra contents are separated from the card by a blue cardboard tray that sits atop the card. Included with the HIS HD 5870 iCooler V Turbo X are two 2x 4 pin Molex to 1x 6 pin PCIe power adapter, a Crossfire Bridge connector, a DVI to VGA adapter, a Steam download voucher for Call of Duty Modern Warfare 2 and small folder that holds the Software CD, quick installation guide and a Case badge.

The card itself is quite imposing with its large black cooling surround. You can instantly see the Modern Warfare 2 graphics adorning the cooler and of course the HIS card title.

Center of the cooler, above the GPU, is the iCooler V's fan; a blue translucent fan with a HIS logo center. The interior of the cooler is aluminum fins on top of a copper core. At the back of the cooler there are sports car like vents.

Tucked under the vents at the rear are two PCIe power headers.


The back of the card is pretty uneventful but you get a good look at the blue colored PCB that HIS use.


Moving to the IO slot, we can see that HIS have used a gun metal coloring for the plate which gives it a more business like appearance. For IO, we have two DVI ports, an HDMI port and a DisplayPort port. You can also see a half sized exhaust area.

Overall, the HIS HD 5870 iCooler V Turbo X looks great, and we've seen in the past that the iCooler performs well, so let's put this card to the test shall we?


Test Setup: Intel Core 2 Duo 6420 @ 3.20GHz, 4GB of OCZ PC2-6400 Ram @ 960MHz, Asus Blitz Formula, Silicon Power M10 32GB + Seagate Momentus XT, Asetek Waterchill Watercooling, Hiper Type M 730w PSU. All latest drivers as of July 2010 and the OS is Windows 7 64bit.

For comparison, we are testing against a default clocked 5870 card.


Left 4 Dead 2 - Recording a custom demo on the Dead Center, Hotel level (inside in the inferno), we used FRAPS to record frame rates as we played back the demo on all cards at same settings.

Assassin's Creed 2 – The second of our DirectX 9 games, we tested by climbing a tower repeatedly in the Venice, San Polo – Rialto Bridge area and taking a leap of faith to the hay below 3 times. FRAPS was used to record frame-rates and the cards were set to the highest possible for each card.

Batman Arkham Asylum – We used a combination of the in game benchmark and FRAPS to gather our numbers for this game. All cards were set to the highest possible settings for that card.

Crysis Warhead – We used the Framebuffer benchmark tool to run through the Ambush demo and recorded the results with FRAPS. Settings for each card were set to highest possible for that card.

Aliens vs. Predator Benchmark – Recently released and using a DirectX11 engine, this benchmark provides a nice repeatable test combined with FRAPS. Settings for each card were set to default benchmark settings.

Colin McRae's DiRT2 - DiRT2 has some very good looking visuals and provides us with another DirectX 11 test. We used FRAPS with the games inbuilt benchmark to test a quick run around a London track.

S.T.A.L.K.E.R: Call of Pripyat Benchmark – Our third DX11 test uses a combination of FRAPS and the Ray portion of the benchmark. Cards were set to highest possible for each card.

Devil May Cry 4 Benchmark - DMC4's benchmark provides a nice way of testing that anyone can do. Results are all from the benchmark itself, and include average frame rates as well as 4 graphs for each level tested. Settings for all cards were the same.
