Diamond HD4870 1GB Review

» Discuss this article (1)


The Diamond HD4870 video card with 1GB of GDDR5 RAM, has a great stock cooler installed on it, as it is able to keep it cool while under load as well as when it is idle. The card never went much over 85°C, which is higher than some of the other cards out on the market, however there is more dense and hotter memory modules on the Diamond card than others that made the temperatures higher. The dual slot design of the Diamond HD4870 card is both a good thing as well as a con as it does allow for a thicker stock cooling device, however it does make the card bulkier than if it had a slim card. By being that thick, it does cut into the amount of room and depending on how the motherboard it is being installed on is setup, it may not allow you to have a second card installed. The 1GB of GDDR5 installed on the card is a great addition to the card, allowing it to have more even scores across the different resolutions, however with its increased power consumption, it did take a decrease in the overclockability of the card. The performance of the card was also fairly straight across the board; the results from the benchmark testing were pretty much even with each other, there was not any that were significantly higher than another one. The scores however were all quite lower than I was expecting, I had expected the Diamond card to beat the other cards in its class by a decent amount. By the same token the HD4870 cards that it was compared against were both overclocked cards with clock speeds above what was possible with this card. So if you look at the overclocked scores on this Diamond HD4870 1GB card you will get a true picture of the benefits that 1gb of frame buffer adds to the equation. With that taken into account the performance is shows a nice increase across the board. I would suggest this card to anyone who is looking for a great looking card with a possibility of improvements. If you are looking for a project, you could pick this card up, perform a volt mod to supply more power to the core and the memory to be able to overclock them higher and the scores should go up quite a bit during the higher resolutions. Or if you are looking for a great card that is going to help you get higher scores than you older card, I would recommend this card as well.
