8800GTS shootout - XFX 8800GTS XXX vs Gainward 8800GTS "Golden Sample"

Introduction and Specification

Introduction

Many of Nvidia's partners have decided to bump the clock speed on the 8800 parts quite recently. This is a great way that customers can get their hands on some overclocked parts that still have a warranty intact. With this in mind we got in a couple of rather speedy 8800GTS to thrash through our tests.

Let's see how they got on...

GeForce 8800

nVidia released the G80 series of GPU's back in November last year and took the market by storm, totally outgunning everything out there. With full (and well implemented it has to be said) DirectX 10 support and steaming DirectX 9.0c support the enthusiast market has lapped these blazingly fast GPU's up like hot-cakes.

Having previously reviewed both the 8800GTX (click) and the 8800GTS (click) , I am approaching this review in a slightly different manner to usual, as you will see later on.

In the meantime let's take a look at the basic specs of the 8800 series.

Overclocked

Now XFX and Gainward have gone a few MHz better than these stock speeds of 500/1600 going up to 550/1760 for the Gainward Bliss "Golden Sample" Edition and 550/1800 for the XFX "XXX" Edition. It's also worth noting that XFX have overclocked the stream processors on their XXX Edition to 1500MHz, as compared to 1200 at stock. The gainward card is running at the stock 1200MHz (according to RivaTuner ).

The stream processors in the GTS were cut down from 128 to 96 and as such we've seen more clock speed increases throughout the GTS range as they seem to have that little bit extra to squeeze out of them. This also means that the overclocked GTS are getting close to the performance of the GTX.

Let's take a look at the cards.
