The Sapphire Radeon HD 4850 TOXIC

Final thoughts and awards

Through its preferred range of etailers, Sapphire is charging around £150 for a Radeon HD 4850 TOXIC EDITION 512MiB graphics card. The question is, we suppose, why would you pay a significant premium for it when a reference card can be purchased for around £120?

The TOXIC's attributes are more than just a flashy name, however. Pre-clocked to 675MHz core and 2,200MHz memory, a healthy increase over stock clocks of 625MHz/1,986MHz, the TOXIC benchmarks nearly 10 per cent higher than the el-cheapo '50s. That increase is facilitated by the bolting-on of an aftermarket ZALMAN heatsink that provides welcome relief from the whiny reference heatsink and its hunk of heatpipe-driven copper cooler keeps the underlying GPU some 16°C cooler.

HEXUS is always partial to manufacturers doing their bit to improve on the reference design, and Sapphire clearly has, but the only major fly in the ointment lies with the pricing. At £150, the common etail outlay, it begins to impinge upon the very cheapest Radeon HD 4870s, which are intrinsically faster SKUs.

Our advice would be to put it for on your short-list if you want a capable graphics card that goes about its business in a quiet, efficient manner. Performance is suitably solid, provided by the underlying architecture, and the inclusion of the ZALMAN heatsink is a sensible method of differentiating it from the crowd.
