XFX Radeon HD 4890 1GB XXX Graphics Card Review
Written by Mavke   
Monday, 06 April 2009

Today AMD recently announced its newly RV790 based Radeon HD 4890 card, and you should know that their RV790 is an improved version of the RV770 you might know as the Radeon HD 4870's ticker. The basic specifications are still the same and the only changes the end users should be aware of were done on the clocks. The Radeon HD 4890 runs at 850MHz for the core, which was tough to reach with the Radeon HD 4870 even with water cooled versions. This new GPU is much more flexible and allows us to overclock the core to +900MHz. This is the reason why AMD allowed its partners to launch overclocked boards on day one, and XFX isn't the one to miss out on such opportunities. - FudZilla

Gainward GeForce GTX 275 896MB Cool Card Review
Written by Mavke   
Thursday, 09 April 2009

Our today's guest is the GeForce GTX 275, the card announced on the same day as AMD's Radeon HD 4890. These two cards promise to be fierce competitors, and if you are planning on splashing out about $249 to buy a graphics card for gaming, any of these two will surely do you good. While the Radeon HD 4890 is currently AMD's best single GPU board, where the GeForce GTX 275 found its place between the GeForce GTX 260 and NVIDIA's fastest single GPU board, the GeForce GTX 285 edition. Now the GeForce GTX 275's chipset is made in 55nm, has 240 shader processors, uses a 448-bit memory interface and comes with 896MB of GDDR3 memory and is as such a nice mix in between. - FudZilla

NVIDIA GeForce GTX 275 OverClock Upgrade Review
Written by Mavke   
Wednesday, 08 April 2009

Recently we looked how the Radeon HD 4890 from ATI went in the overclocking department. Though today we take a closer look at how NVIDIA go with the new GeForce GTX 275 which has just been recently released to compete against the new ATI offering. While overclocking on NVIDIA cards is slightly more involved due to the fact that the drivers don't have any embedded overclocking software, these cards do only require the installation of a small program called RivaTuner to get around this. With RivaTuner installed and plenty of spare time, we went on our merry way to increasing the memory and core clock to a point which gave us a nice increase in performance, whilst still being completely stable. - TweakTown

ASUS Extreme AH4890 1GB Video Card Style Review
Written by Mavke   
Tuesday, 07 April 2009

As you might have guessed, ATI's new Radeon HD 4890 graphics board is well placed to compete with enthusiast video cards just like their Radeon HD 4870 1GB and the GeForce GTS 260 Core 216 edition, as well as the rather recently released GeForce GTX 275. In terms of performance, the Radeon HD 4890 has the potential to beat all of the above, with its most direct competition coming from the more expensive GeForce GTX 285 graphics card. These are the fastest single GPU cards available on the market today, and are all more than powerful to handle gaming on anything less than a 30inch wide LCD display. For smooth gaming at extreme resolutions, a multi GPU setup is the best option. - PCStats

Sapphire Radeon HD 4890 OverClock Version Review
Written by Mavke   
Tuesday, 07 April 2009

Alright time for a refresh, it's almost spring and that's just the season for growing graphics cards. So the Radeon HD 4890 is, for all intensive purposes, a retooled Radeon HD 4870 which in our humble opinion, is overdue. Not that the Radeon HD 4870 was by any means a bad card, and it certainly got its deserved amount of press, but it had its failings and when prices were even we would generally just recommend the GeForce GTX 260 edition. Prices rarely were even, fortunately or unfortunately, depending on who you like to root for. Although on the pretty good chance that you were getting a Radeon HD 4870 because it was cheaper, it was easy to overlook its major shortcomings from the total view. - TechLounge

ASUS Extreme AH4890 TOP 1GB Card Design Review
Written by Mavke   
Monday, 06 April 2009

But faced by an economy in recession, it could be smarter to refine the products you have than to design and produce new ones. And this is the basis for our introduction, and the concept behind AMD's business strategy for the discrete graphics market. Which raises this question, should a video card manufacturer improve and perfect their current products, or should they rather spend money they can't spare on a new design? AMD has decided to hone the RV770 GPU and offer the RV790 chipset as a result, while the competition is pledging itself to expensive and unnecessary ultra high-end products for a shrinking market. And ASUS is ready to jump on the wagon with their version. - Benchmark Reviews

Gainward GeForce GTX 275 Graphics Version Review
Written by Mavke   
Monday, 06 April 2009

It's been a while since we have had one of those horrible launches, but it doesn't come as a surprise that NVIDIA are the first to have one after all this time. Over the past two weeks there's been a war between NVIDIA and AMD in regards to NDA times on the Radeon HD 4890 and GeForce GTX 275 graphics cards. We've had Radeon HD 4890 samples coming in for a few weeks now. So with that said, we chose not to test the card straight away, because as we draw closer to NDA we see new drivers come out. The Radeon HD 4890 was originally set to release two days before the GeForce GTX 275, and ATI then put their pedal down some more and it was released almost a week early than expected. - TweakTown

NVIDIA BIOS Editor (NiBiTor) v5.0 Software Released!
Written by Mavke   
Sunday, 05 April 2009

Well we have has just released a new version of NVIDIA BIOS Editor (NiBiTor) software. NiBiTor is the original and definitive BIOS tweaker that supports the latest NVIDIA graphics cards, and which is updated on a regular basis. NiBiTor allows graphics card enthusiasts, or the hardcore overclockers to have full control over some advanced features and functionality found on firmware of supporting cards. And doing so users gain some extra performance, enable certain hidden features, tweaking memory latencies, provide extensive information, adapt bootup settings, changing fan speed options and/or get extra stability on their NVIDIA based graphics accelerators which will just give them that little extra value.

NVIDIA GeForce GTX 275 896MB Video Board Review
Written by Mavke   
Thursday, 02 April 2009

After the setback inflicted upon them by ATI's Radeon 4800 series, NVIDIA has been slowly but surely picking themselves up. Sure, they were left floored by the sheer value for money proposition that ATI was touting, but like real men, they licked their wounds and soldiered on. Since then, they've been hard at work. Their GeForce GTX 295 stole the speed king crown from ATI's Radeon HD 4870 X2 and with a new pricing strategy and improved products in the form of GeForce GTX 285 and GeForce GTX 260 Core 216, they gave gamers looking for high-end graphics solutions something to really think about. Though luckily for them, their choices of high-end card have just become a little more varied. - Hardware Zone

Sapphire Radeon HD 4890 1GB Graphics Card Review

Wednesday, 01 April 2009

Today AMD announced their newest Radeon HD 4890 series. It is based on their RV790 GPU which is an improved version of the RV770 chipset. And the major cornerstone specifications have remained the same, only improvements related to clock frequencies have been made. While it was almost impossible to get an RV770 to run far beyond 800MHz, the new ATI Radeon HD 4890 reference runs at 850MHz core by default. Many partners will be offering overclocked boards as well ranging up to 1000MHz core speeds. Now while AMD has been sending out overclocked cards running at 900MHz, our graphics cards are just based on the reference design clocks of 850MHz though can be overclocked. - techPowerUp

Gigabyte Radeon HD 4890 1GB Version Card Preview
Written by Mavke   
Wednesday, 01 April 2009

The Radeon HD 4890 is an interesting board, but we haven't heard loads about it and the general excitement about the card is quite low. But the main reason we think people aren't that excited is because both they and we know that the card isn't going to be as fast as the dual GPU wielding GeForce GTX 295. And this is what most people want, especially when the Radeon HD 4800 series cards have been out for so long. The Radeon HD 4890 though should do what ATI does best lately, offer good performance at a pretty good price. The board wasn't due to be released, but due to NVIDIA having the GeForce GTX 275 coming out a few days earlier, the launch date for this card has been moved forward. - TweakTown
