New Revolution: ATI Radeon HD 4770 Graphics Card Review
April 28, 2009 by Cabro · Leave a Comment
Everyone remembers the revolution made by Radeon HD 4850 that has set a new performance bar for mainstream graphics accelerator. Today AMD officially launches a new revolutionary, this time from the Budget segment.
So, Radeon HD 4770 announced today, on April 27, 2009, became this new solution. ATI often testdrives some technological innovations on inexpensive graphics solutions first and Radeon HD 4770 is no exception: it is based on RV740 – the world’s first graphics processor manufactured with 40nm process. It is also the first budget graphics adapter equipped with GDDR5 memory. The new solution promises to be pretty exciting from all standpoints that is why our today’s review will try to reveal if the new Radeon HD 4770 can really perform a revolution in the budget gaming segment. But at first let’s check out the technical details.
ATI Radeon HD 4770 40nm GPU, $99 Graphics Return
April 28, 2009 by Cabro · Leave a Comment
AMD is launching yet another new ATI Radeon graphics card today. And in light of the current worldwide economic conditions, along with the performance and power consumption data we’ll be presenting you on the proceeding pages, we suspect it’s going to be a welcomed addition to the company’s already potent graphics card line-up.
You see, the brand new Radeon HD 4770 is AMD’s first mainstream desktop GPU manufactured using a 40nm process, and as such, it is more economical for the company to produce (with a smaller die size) and it consumes little power relative to the current crop of products manufactured at 55nm. The Radeon HD 4770′s main features don’t stray far from the other members of the Radeon HD 4000 family, but its specifications are somewhat different due to the use of a new GPU, which was formerly codenamed RV740.
Now then, what if we told you this new lower power GPU also drops in at a miserly $99 price point? Are the days of the reasonably powerful $99 graphics card back, you ask? We’ll answer that question for you in the pages ahead but in the mean time, the Radeon HD 4770′s main features and benefits are listed below for those of you who like to see all of the gritty details. We’ll discuss the card itself and its overall performance a little later. Take a look…
Graphics Card Failure Rates
March 23, 2009 by Cabro · Leave a Comment
We found this interesting article and thought it would be useful to translate for our English speaking readers.
We finish our series of current events on the failure rates with the graphics cards and GPU. These statistics are always those of a large French E-tradesman. They relate to the charts sold from March to August 2008, that is to say 6 months 1 year from operation. The statistics by mark are based on a minimal sample of 500 sales:
- ASUSTeK: 2.0%
- Sapphire: 2.0%
- MSI: 2.1%
- Leadtek: 2.4%
- PNY: 2.8%
- Gainward: 3.2%
- Gigabyte: 3.6%
- Point Of View: 5.6%
The failure rates are overall normal, except Point Off View which is notably less good. If the least reliable models more closely are looked at, one finds two charts with the top of 10% which were sold with more than 100 specimens: Gigabyte GV-RX26P5H, Radeon HD 2600 passivates, is to 14.1%, against 10.2% for ASUSTeK ENGTX280/HTDP/1G. If one looks at the rates of return by GPU, one arrives at the following figures:
- GeForce GTX 280: 9.9%
- GeForce GTX 260: 4.3%
- GeForce 9800: 3.2%
- GeForce 8800: 3.3%
- Radeon HD 4870: 3.2%
- Radeon HD 4850: 1.9%
- Radeon HD 3870: 2.6%
In spite of the high temperatures reached on Radeon HD 4870/4850, these last have completely normal failure rates. A contrario the GTX 280 are not the queens of reliability. Concerning the charts Bi-GPU, one is to 6% for the 9800 GX2, 11% for the 3870 X2 (!) and 4.3% for the 4870 X2.

AMD to demo GPU physics at GDC next week
March 23, 2009 by Cabro · Leave a Comment
AMD might have publicly declared its support for Havok’s gaming physics technology, but the company has been curiously quiet about GPU-accelerated physics since Intel bought Havok in 2007. Since then, AMD has revealed that it’s still working with Havok, but has only really talked about running Havok on AMD’s x86 CPUs. However, AMD has now revealed that it plans to demonstrate its own GPU-accelerated physics technology at the Game Developers Conference (GDC) next week.
AMD’s Catalyst product manager, Terry Makedon, revealed on his Twitter feed that AMD would reveal its “ATI GPU Physics strategy,” and added that there may also be “a demo being thrown down next week at GDC.” Makedon also said that “Havok is indeed our partner of choice,” when asked about the talk. The 60-minute talk, called “Having Your Cake and Eating it Too: Increasing Game Realism, Scale and Reach” will take place at GDC on 26 March.
The summary for the session says that AMD will discuss “the latest on game computing featuring open, standards-based physics with OpenCL and ATI Stream.” AMD’s stream computing director, Patti Harrell, explained to us a while ago that “the beauty of Havok is that ultimately we would expect it to sit on top of these industry standard APIs as they become available. So we’re working with them, and in fact there’s a team in our consumer group who works very closely with them on a daily basis.”
AMD found itself in a difficult situation after Intel bought Havok and Nvidia bought Ageia, and the company claimed that talks about GPU acceleration using the Havok FX API effectively broke down after Intel bought Havok. Since then, the focus for AMD has been CPU support for the physics API. At the time, Havok’s managing director, David O’Meara, explained the priority for CPUs, saying that “the feedback that we consistently receive from leading game developers is that core game play simulation should be performed on CPU cores.”
However, he added that GPU physics acceleration could become a feature in the future, saying that “the capabilities of massively parallel products offer technical possibilities for computing certain types of simulation. We look forward to working with AMD to explore these possibilities.”

AMD HD 4850 – RV770 GPU die shot
June 6, 2008 by Cabro · Leave a Comment
Never, ever leave a bit-tech person in reach of a screwdriver and an unattended next generation graphics card; otherwise this happens. People, there’s your RV770 core, the eight Qimonda memory chip layout and general red PCB goodness.
Photoshop to get GPU and Physics Acceleration
May 23, 2008 by Cabro · Leave a Comment
Santa Clara (CA) – GPU acceleration is one of the most significant trends in today hardware industry, opening the doors to an entirely class of software running desktop. What will be possible is fascinating to see on a monitor, nut it is not tangible, if you just hear about it. It appears that the next Photoshop will be one of the first mainstream applications that will tap into the GPU for a speed up. And, at least from what we have seen during a first demonstration, the progress is simply stunning.
