Testing:

I am very interested and excited to see how the new Sapphire HD4870 Toxic from ATI will compare when it is tested using a few different video benchmarks to measure the card's performance. I will be putting the Sapphire card up against a few different video cards that are out on the market, including the PowerColor HD4850. I am also extremely interested in seeing how the cooling solution Sapphire has added to its HD4870 is going to handle the temperatures. All of the settings will be set at stock for all of the cards; I will also be overclocking the HD4870 to the maximum level so that I can compare the difference in performance when overclocked, and see how beneficial it is to overclock all components in your system.

Overclocking:

Overclocked settings:

  • Sapphire HD4870 Toxic: Core - 850MHz   Memory - 1200MHz

There is a two part answer to how well the Sapphire HD4870 Toxic was able to overclock, this is due to the fact that when you get the card, it comes overclocked from the factory at 780MHz for the core and 1000MHz for the memory. So you have a 30MHz overclock on the GPU as stock settings and 100MHz overclock on the memory as stock settings. If you go from how it comes right out of the box, I was able to get an extra 70MHz on the GPU and 200MHz on the Memory, which may not sound like all that much of a huge overclock, however when you add up what you have actually gotten over any other regular HD4870, you get an extra 100MHz on the GPU and 300MHz on the memory.

When it actually came down to the work of overclocking the Sapphire HD4870 Toxic, it was very quite simple. I was able to achieve the overclock I got by increasing the core by 10MHz every time until I hit 860MHz, it became unstable, so I backed down to 850MHz, which was where it was stable. I then moved on to the memory, which was quite simple as well; I was able to overclock using an increase of 15MHz and the maximum I was able to get stable was 1200MHz. The fan that is included with this card is very quiet, and at the 850MHz/1200MHz overclock, the highest temperature that I saw as 62°C, so the VaporX cooling solution really did do the trick in keeping the temperatures in check.
