Product Rating: 4 star(s) Sapphire ATI Radeon HD 4850 Toxic Edition review

Comments:
With the Sapphire ATI Radeon HD 4850 Toxic Edition, Sapphire delivers an enhanced ATI 4850 graphics card with a boosted clock speed and effective Zalman cooler.

Review Verdict: The Sapphire ATI Radeon HD 4850 Toxic Edition is a great value card that is significantly enhanced by the addition of the Toxic elements. The tweaks are enough to turn the Sapphire HD 4850 from a chip that's ever so slightly slower than the 9800 GTX to on

Preview: Radeon HD 4850 CrossFire Performance

Comments:
The much awaited Radeon HD 4850 graphics cards have actually landed in retail this week and despite the oddity that it hasn't launched yet officially, we managed to grab two of these newcomers to give you a preview of what they taste like. Check them out

Review Verdict: The Radeon HD 4580 graphics card is the first out of the new 4000 series stable of graphics cards using the RV770 GPU core. The Radeon HD 4850 uses the RV770 PRO SKU while the higher-end 4870 model will follow shortly using the RV 770 XT part

Sapphire Radeon HD 4850 TOXIC: better than reference

Comments:
During a busy June 2008 both NVIDIA and AMD debuted their next-generation graphics cards - GeForce GTX 268/280 and AMD Radeon HD 4850/4870, respectively

Review Verdict: 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...

Sapphire Radeon HD 4850 512MB Toxic Video Card

Product Rating: 4 star(s) Sapphire Radeon HD 4670 512MB review

Comments:
While there are cheaper versions of the 4670 available, Sapphire has given ATI's HD 4670 the VIP treatment to make the best sub-£75 deal we've seen yet.

Review Verdict: With Christmas only a couple of months away, we can expect a number of budget cards to rewrite the sub-£75 graphics card market, but right now the Sapphire Radeon HD 4670 512MB is the touchstone, and is certainly a superior deal to the 9600 GT and 3...

Sapphire Radeon HD 4850 X2: another AMD-based thorn in NVIDIA's side

Comments:
Introduction Nearly three months ago, AMD laid claim to the world's fastest mainstream single-board graphics card with its Radeon HD 4870 X2 - a benchmark-pummelling solution that takes two Radeon HD 4870 GPUs and slaps them together on one board wit

Review Verdict: Final thoughts and rating 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

Comments:
Sapphire has strapped two of our much loved HD 4850 cores onto a single PCB. Disaster or genius- - Let's check it out.

Review Verdict: It doesn't come as any real surprise that the HD 4850 X2 is a winner. The whole HD 4800 series from ATI has been impressive and we didn't think this card was going to be any different. It's great to see that Sapphire has jumped straight onto the HD 4850 X

Sapphire Radeon HD 4870 X2 ATOMIC: the fastest gets faster

Introduction AMD's Radeon HD 4870 X2 has comfortably held the title of world's fastest single-board graphics card since its arrival in August 2008. By squeezing two Radeon HD 4870 1GB GPUs onto a single PCB and hooking them up via internal CrossFire, i

Ati HD4850 Roundup

Comments:
Today we are going to get a bit more familiar with some of the more interesting HD4850-offerings. All of these cards feature an improved cooler, higher frequencies and better performance than the reference cards.

Review Verdict: It's great to see some more competition on the graphics markets once again as AMD is back in the game with the RV770 based cards. The effects of competition could easily be seen as Nvidia was forced to lower its prices radically after the HD4K series was

Product Rating: 4.4 star(s) Sapphire Radeon HD 4850 X2 2048 MB

Comments:
Being priced at reasonable $419, the Sapphire HD 4850 X2 is designed to take some market share from NVIDIA's GTX 280. The card features 2 GB of GDDR3 memory and comes with a custom designed cooling solution. Even though you would expect very little overcl

Review Verdict: When looked at from a pure performance standpoint, then the Sapphire HD 4850 X2 is among the top cards on the market. It beats the NVIDIA GeForce GTX 280 by about 3%. What is also very interesting is that in higher resolutions the HD 4850 X2 can also beat

Comments:
Sapphire has engineered their own version of the Radeon HD 4850 with cost and cooling in mind. The card's new unconventional heatsink looks good and keeps the card cool - far below reference design temperatures. The best of all is that the card costs only

Review Verdict: Sapphire's own HD 4850 design seems to be designed with cost in mind. The card is currently the cheapest HD 4850 card available online which alone will be very appealing to many users. On the other hand for just a few dollars more you can get features lik

Product Rating: 4.6 star(s) Sapphire HD 4850 Toxic 512 MB

Comments:
Sapphire's new HD 4850 Toxic graphics card comes with a preinstalled Zalman VF-900 GPU cooler that greatly reduces the operating temperature of the card. Also the operating frequencies have been bumped quite a bit, with some additional overclocking potent

Review Verdict: I have a bit mixed feelings about the Sapphire HD 4850 Toxic. The inclusion of the Zalman VF900 cooler is a great choice, but the fixed fan speed is not. Since the fan is always running at the same speed of around 1700 RPM, it will obviously lower the idl

Comments:
We've all been wondering about Shane's love for the HD 4850 in Crossfire, today we figure out what it's all about.

Review Verdict: I absolutely love this card and the performance it offers. Considering stock is already available and the price is nothing short of fantastic, there isn't a whole lot not to get excited about. Sure, it's not a GTX 280 killer at all points, or even a 9800
