Sapphire poisons HD4870
SAPPHIRE TECHNOLOGY has announced its new HD 4870 Toxic Edition high performance graphics card.
“Overclocked out of the box” is something Sapphire toxic card punters have come to expect and the new HD 4870 TOXIC Edition certainly doesn’t disappoint.
Boasting 512MB of GDDR5 memory, clocked at 1000MHz (4Gbps effective) and with a pre-overclocked GPU core at 780MHz, Sapphire reckons it has given users plenty of “scope for performance tuning”. So you can leave the liquid nitrogen in the freezer.
The firm is also mighty proud that its new offering supports AMD CrossfireX and that the two high speed connectors on each card allow for two, three or even four cards to be “daisy-chained” together when installed in a suitable CrossFireX mainboard.
And if we’re talking cool, we should mention that the HD 4870 Toxic Edition comes complete with a Vapor-X cooler. This uses Vapour Chamber Technology (VCT), three heat pipes and a thermally-controlled fan for what, the firm reckons, will be markedly “more efficient and quieter cooling”.
The only thing Sapphire neglected to mention in its release was how much a Sapphire Radeon HD 4870 TOXIC would set you back, but no doubt we will find out as soon as they hit shelves any day now. µ

The standard 4870 overclocks to 785/1050 out of the box and is still pretty quiet....seems like money for old rope to me....
The overclock is ok. 

Sapphire also makes a 4850 with 1GB of memory. This is the first 4xxx series with more than 512MB of ram aside from the X2. Its a more niche product than an overclocked card, but its great seeing Sapphire step up and doing it! For anyone doing GPGPU memory speed may not be all that important (particularly anyone doing double precision floating point work) but the memory size will make or break a lot of applications.
