Chances are pretty good that you have just read our ATI Radeon HD 4890 1024MB review, as well... ATI has something new to offer for you guys in a 270 USD price level segment. Obviously, as expected, NVIDIA was awaiting that release and on the very same day decided to launch a new product onto the market as well. The product is the one you guys obviously heard about for a while now, the GeForce GTX 275.

Positioned slightly cheaper compared to the new ATI product, NVIDIA launches the GeForce GTX 275 as a reaction to show and flex their rendering muscle. Now I know that some of you guys might think otherwise, but trust me when I say, this is a really interesting move from NVIDIA as there is a trick or two going on this new GeForce GTX 275.

First of all it's using the very same 55nm GPU as the GeForce GTX 285, with the full 240 Shader processors. With that in mind try to imagine the GeForce GTX 285 with the memory configuration of a GeForce GTX 260, 896 MB 448-bit...  and there you have your GTX 275.

Now here's the really interesting thing. The GTX 275 cards are clocked fairly high on the core and shader domains (compared to the GTX 260), making this product very fast. In fact it will even come close to the GTX 285, yet at a significantly lower price, that price being 249 USD or 239 EUR.

So all in all this is definitely stuff interesting enough to check out we say! This article will go over the reference model GeForce GTX 275, armed with 896MB of memory. We'll take it head to head against ATI's latest offering, the Radeon HD 4890, and will see what the GTX 275 brings to the table in terms of value for that hard earned commodity of ours, money.

Have a peek at the actual product below, and then we'll dive into an overview, specifications and well... all other tests. Grab some coffee,

GeForce GTX 275 shootout BFG | Inno3D | Palit | Sparkle

A week or two ago NVIDIA announced it's latest graphics card positioned in the high-end region, called the GeForce GTX 275. The GeForce GTX 275 is a bit of a hybrid card in-between the GeForce GTX 260 and GeForce GTX 285.

The card is positioned directly against the new ATI Radeon HD 4890, yet is slightly cheaper. NVIDIA launched the GeForce GTX 275 in an allergic reaction to team red's product to show and flex their rendering muscle. Now I know that some of you guys might frown a little about this GTX 275 release, but trust me when I say, this is a really interesting move.

The GeForce GTX 275 has the very same graphics processor as that GTX 285, yet the memory configuration of the GTX 260 (896 MB). Fitted on a new PCB and armed with a dandy cooler NVIDIA did another thing, they lowered prices significantly.

The GTX 275 is a card that is being introduced at a 239~249 USD price level. And though features and performance wise the product is not exactly the reinvention of the wheel, it definitely is a massive load of performance at a very fair price. At the time of writing this article it's two weeks after the launch and the first retail products are now hitting the stores in reasonable volume.

As such we figured to cease the moment and show you a couple of retail boards. For this article, a total of five GeForce GTX 275 graphics cards will be put to the test. We take the NVIDIA reference sample, two reference clocked products and two pre-overclocked products to see where we are at in terms of performance, cooling and features among the difference AIB/AIC partners.

We'll take the BFG GTX 275 OC edition, the Inno3D Overclock editions GTX 275, the Palit GTX 275 with custom cooling and the all reference based yet blue'ish colored GeForce GTX 275 from Sparkle.

We'll compare each AIB card at it's default clocks and compare it to the reference model. Of course, you are on .. we'll also overclock all cards tested today to investigate and observe what the limit of each product really is. First we start off with a quick introduction of the GTX 275, the differences, the new, and the not so new ....

GeForce GTX 275 Overclock

So you picked up this GeForce GTX 275 for 229 EUR, a card full of livelihood, performance and bang for buck. But heck, you are guru ... you want more. And of course that is possible. Very soon you will see overclocked models of the GeForce GTX 275 released by many board partners. These pre-overclocked models will be roughly clocked at 650MHz core, 1475MHz on the shader domain and 1200MHz (x2) on the 896MB GDDR3 memory. With the exception from BFG (OCX) and eVGA (SSC) of course, which will go even higher.

But why not do this yourself ? Overclocking is a relatively easy thing to do if you follow some basic guidelines.

Overclocking can be managed in many ways, through the NVIDIA control panel center or third party software. In this article we'll show you how you can overclock the easy way, with the help of Rivatuner.

This article is really simple as all we'll show you is, how to manage this .. and of course throw in a couple of additional benchmarks. See this as an easy overclocking guide, which is a series we'll start more and more with newer graphics cards.

What is overclocking ? Your graphics card has clock generators that allow several 'domains' on your graphics card to be clocked faster. In current days there often is a lot of overclocking headroom. Because not only does a product need to have a safety tolerance, pre-overclocked graphics cards actually became a market to sell in.

The GeForce series has 3 domains we can play around with and try to clock faster. The core (ROP) domain, the shader processors domain and the graphics memory. Clocking these domains faster (MHz) often can result in performance increases of 5 to 10%. And in the land of graphics, that's the difference between fast and furious..

In our vision, the best tool for overclocking NVIDIA and ATI videocards is Rivatuner that you can download here at, we actually make this software, we know what we are doing.

So what are we doing today? :
Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its compute clock cycles per second. It sounds hard, but it really can be done in less than a few minutes. I always tend to recommend to novice users and beginners not to increase the frequency any higher then 5% (in total) of the core and memory clock MHz. But heck, just read our guide here and see for yourself.
