Conclusion: As we mentioned in our introduction, it's been quite a long wait for the Radeon HD 4850 X2 to hit retail, but thankfully Sapphire have finally brought us out of our misery by introducing this SKU themselves - so, has it been worth that several month wait? In a word, yes - The lack of direct competition for NVIDIA's GeForce GTX 280 has been arguably one of the biggest chinks in AMD's graphics board line-up ever since the Radeon HD 4800 series first saw the light of day,...
Sapphire Radeon HD 4850 TOXIC 512MB video card review
25 March 2012
Conclusion: As we mentioned right at the start of this article, we already know plenty about what makes the Radeon HD 4850 such a tempting graphics upgrade proposition, thus today's question is - What makes Sapphire's TOXIC board a better choice? From a pure clock speed point of view the Radeon HD 4850 TOXIC only really succeeds in improving clocks to broadly the same level that we've already seen on other reference-based boards via overclocking, so if you're happy to overclock a...
Conclusion: Well, what a difference a new graphics architecture makes. Ever since the dawn of the DirectX 10 era, we've been mired in disappointment when it comes to AMD's graphics solutions - While they've often managed to provide the exciting new features (such as HDMI support and DirectX 10.1) first, they simply haven't been able to do so at the kind of performance levels that would allow for them to truly challenge NVIDIA on anything more than those particular bullet points.
Sapphire Radeon HD 4850 512MB Vapor-X video card review
25 March 2012
Conclusion: As we mentioned in our introduction, the Radeon HD 4850 has become like a pair of comfy old slippers, so well-versed are we in what it's capable of. In short, gaming at 1680x1050 is a breeze even with anti-aliasing in place, and quite frequently 1920x1200 isn't beyond the realms of possibility either, serving up excellent performance at its particular price point. Then you have top-notch DVD and High Definition playback, DirectX 10.1 support and the like to add the...
Summary: Despite running at a higher clock speed than the 4870-family boards, the GDDR3 on the 4850 transfers half as much data per clock cycle. With a street price that’s less than $300, the 4850 X2 is a great deal for owners of lower-resolution 22-inch monitors. However, if you use a 24-inch or 30-inch panel, it’s probably worth ponying up for a card with a peppier memory pipeline.
Pros: Killer performance for $300. Four DVI ports! Faster than a GTX 280.
Cons: GDDR3 hurts memory bandwidth. Four DVI ports leave no room for rear exhaust vents.
Excerpt: So did Sapphire fill a niche void and provide a card to the consumer that wanted a dual core card without the killer huge price? You bet. This card at around US$275-$300 at the time of this review is a great deal and will have anyone enjoying the latest games with higher resolutions and quality settings while still providing decent framerates.
Summary: Sapphire’s little brother to the HD 4870 X2 is certainly no “red-headed stepchild.” The HD 4850 X2 is able to hold its own in the 3D games and benchmarks we tested… all while looking good, keeping cool and quiet, and doing it for around $300.
Sapphire Radeon HD 4850 X2: another AMD-based thorn in NVIDIA's side
4 November 2008
Conclusion: In a scenario that scales multiple GPUs particularly well, Sapphire's Radeon HD 4850 X2 delivers on AMD's goal of providing the world's second fastest single-board GPU - second only to its own Radeon HD 4870 X2. Unlike the ridiculously-quick Radeon HD 4870 X2, though, the 4850 X2's performance lead isn't quite as clear cut.
