Sapphire Radeon HD 4870 TOXIC 512MB video card review
25 March 2012
Conclusion: Despite all of the praise lavished upon AMD's Radeon HD 4870, no graphics board is ever perfect and thus there is always room for improvement somewhere within its design, leaving plenty of room for AIB partners to come along and right any wrongs courtesy of their own board configurations.
Conclusion: If I were writing this review when both the Radeon HD 4870 and GeForce GTX 260 were at their original launch prices, then concluding this review would have been simplicity itself, allowing me to hit the save button and go and grab something caffeinated in no time. Quite simply, with the GeForce GTX 260 priced so much higher than its closest rival, and given the performance metrics of these two boards, the Radeon HD 4870 would have been the card to purchase by a country...
Sapphire Radeon HD 4870 X2 ATOMIC 2GB video card review
25 March 2012
Conclusion: As we alluded to in our opening, it's exciting to see that we've now entered a world of plenty when it comes to the differentiation of AMD's graphics products, and it's frequently Sapphire that we look to as the AIB partner at the forefront of such innovations. When we took a look at the Radeon HD 3870 X2 ATOMIC around nine months ago, we were excited to see water cooling on a high-end AMD graphics board, but otherwise underwhelmed by the implementation - The radiator...
Sapphire Radeon HD 4870 TOXIC 1GB video card review
25 March 2012
Conclusion: Overall, there isn't a really a great deal that we can say about the 1GB variant of Sapphire's Radeon HD 4870 TOXIC that we didn't already cover in our review of the 512MB model. From a performance standpoint it simply adds a little extra gloss to the Radeon HD 4870's already excellent performance, much in line with the HIS part we looked at before Christmas, and that gloss helps it to hold its own against NVIDIA's GeForce GTX 260 Core 216 in pure framerate terms even...
Summary: The cooling performance of this card is out of this world. The fan is practically inaudible with the card in the test rig only a few feet away from me. The temperatures were very low as we've seen and the driver controlling the fan speed does a great job. The Vapor-X cooling has a great benefit for all you overclockers out there.
Cooler temperatures usually equate to higher potential overclocks. Again, this rings true with the Sapphire HD 4870 Vapor-X Edition.
Pros: - Vapor-X Cooling, - Native HDMI, - 800 stream processors + 230GB/sec o memory bandwidth, - Black Diamond - Sapphire choke offers 10% cooler and 25% more power efficiancy than normal choke
Cons: - Hot competition from the many, many other 4870 cards out there., - Price.
Sapphire Radeon HD 4870 TOXIC 512MB: a worthy upgrade?
8 October 2008
Conclusion: Sapphire's Radeon HD 4870 TOXIC 512MB elevated frequencies give it around a 6 per cent advantage in most tests when compared to a vanilla card, shown by the difference in aggregate framerates across the four games. Overall performance, then, sits between a Radeon HD 4870/GeForce GTX 260 (192-core) and a pre-overclocked GeForce GTX 260 (216-core).
Summary: After we reviewed the Sapphire HD4850 we thought
we had seen the best that ATI/AMD had to offer. We found just how wrong we were
when we ran our first test with the Sapphire HD 4870. Here is a video card
that has Nvidia scratching it's head try to find card that will compete with it.
Being a true ATI fan boy I think it is great that the roles have finally been
reverse and for now ATI has the best performing and selling cards available
