Palit use the same, stylish box design on their GTX 670 as we saw on the Jetstream version of the GTX 680 and it looks great. Inside we find a basic bundle with software CD, power cable, DVI to VGA adapter, HDMI to DVI adapter and manual.
Shown above is the Palit GTX 670 which is clearly very different from the 680 as well as the NVIDIA reference card. The first and most obvious change is the use of a cooler which exceeds the dual slot width of the standard card. Attached to the front of this cooler are two 9cm fans, each with TurboFan blade design which is based on jet engine concepts for improved air stream and pressure. In addition to this the fans rotate in the opposite direction to each other, reducing airflow conflicts and enhancing performance. They are also LED models, lighting up blue when the system is powered on.
Underneath the cooler cover and fans we have a large block of aluminium fins and running through them are three copper heatpipes which attach to the GPU block. Also present here is DrMOS technology to offer higher current, lower noise circuits, minimised heat generation, more stable voltages and enhanced overclocking… All sitting on a very compact PCB (similar to reference) which has a bracket on the end to provide stability to the cooler.
In terms of power requirements we have two 6-pin connectors present on the Palit model. These point out the top of the card and are around 2/3rds of the way down the product.
Around at the card outputs we have four present on each GTX 670 with two Dual-Link DVIs starting us off, followed by a HDMI 1.4a and then a full size DisplayPort 1.2 connector. The GTX 670 is capable of running four screens at one time with three available for surround gaming at resolutions such as 5760×1080 and the fourth running off a separate controller for desktop applications such as messaging. It is also worth noting that NVIDIA now offer bezel correction hotkeys for quick in-game changes to show any hidden content and that when setting up three screens we simply click the enable option, follow the simple wizard which allows us to drag and drop the right order making the process easy. As an extra touch the taskbar is now present on the centre display and we can maximise windows to individual screens not just the entire bank of displays.
The reference specifications for the GeForce GTX 670 are 915MHz core (base clock) with a boost clock of 980MHz and the 2GB of GDDR5 memory is set to 1500MHz. Palit opt for 1006MHz base, 1085MHz Boost and 1527MHz memory. There are 112 Texture units within the core along with 32 ROPS, 4 graphics processing clusters and 7 streaming multiprocessors. For the CUDA Cores NVIDIA have gone for a 1344 "core" design and our memory bus is 256-bit (4×64). PCIe 3.0, DirectX 11.1 and DirectCompute are all supported on this card as is acceleration of high definition content and the card can output 7.1 audio over HDMI as well as support PhysX, 4K displays and 3D Vision.
PowerColor offer their own branded version of the liquid cooled R9 295 X2… and now for those who want a similar level of framerate they have their air cooled dual core R9 290X with Devil 13 branding. Today we take a look at this R9 290X2 to see what Powercolor can do with their custom design card in a selection of games including Battlefield 4 and GRID Autosport at 4K resolution.
XFX Radeon R9 280 Black Edition OC Review
It is fair to say that the market for modern Radeon GPUs has been a bit crazy over the last year or so. Their ability to perform currency mining tasks well has impacted sales, availability and pricing significantly but now AMD and their partners...
