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 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...
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...
Conclusion: Sapphire has taken an already powerful card in the HD 4870 and overclocked it. The resulting card is nothing less than superb with the extra cooling that the Vapor-X offers I was able to overclock the card to 810MHz for the core and 1100MHz for the memory. Card temperatures reached 72C when under stress and running overclocked but that is not much of a jump from the 65C that the card would exhibit when idle.
Sapphire Radeon HD 4870 Vapor-X 2GB Video Card Review
5 September 2009
Conclusion: The Radeon HD 4870 is not the newest available card from ATI; the HD 4890 replaced it earlier this year. Performance on the HD 4870 is still excellent for the price. Sapphire went the extra mile with the cooling on the card, rarely going higher than 68C even under the most stressful situations. 2GB of memory really shows off when setting anti-aliasing and anisotropic filtering, as the extra memory gets used in those situations.
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.
Conclusion: . They have all of the standard Radeon features present such as 7.1 audio over HDMI, Blu-Ray acceleration and DirectX 10.1 but the addition of a brilliant cooler keeps noise and heat to a minimum. disappointment about Sapphires 4870 2 GB card it is that it would have been nice for them to push the clocks higher and ship as an enhanced model.
