ATI- Radeon HD 2900XT Reviews On Net.

Filed under: AMD, ATI, Nvidia, PC Games — Ramajay @ 9:01 am

The results from the reviews are as described in our earlier post here. The card is a disappointment to those hoping for a frame rate monster and does not compete in the high-end with Nvidia’s 8800GTX card based on pure gaming performance.

The summary from various reviews is that the card performs about the same as the Nvidia 8800GTS in most games. The 2900XT ,however, draws an alarming 200W of power under load and ATI/AMD recommends a 550W powersupply at minimum and a 750W power supply if you are thinking of a crossfire solution. The card is longer than the GTS and in addition to this immense power draw it requires a large cooler which one review site described as a mini A/C unit. The 2900XT has been reported to idle at around 70c and peak at 84c when under load during a 3DMark2006 benchmark.

Nvidia now owns the high-end, and we did not see an offering from ATI that matched the performance improvements of the old 9700 series of graphics cards which totally eclipsed Nvidia FX series for an entire generation all the way up to the X800 XT cards vs Nvidia’s 5900 Fxs.

The 2900XT does offer the usual great image quality from ATI, with some new modes such as HQ Anisotropic rendering and CSAA modes faring quite well in image quality testing. The card also delivers HD right out the box which allows you to view 1080P HD content with just a 10-15% impact on your CPU as the entire decoding process is managed on the graphics card itself. Potential buyers also need to take into account that these cards come standard with High Def HDMI connectors which provides HDCP immediately, with sound. ATI also arranged a bundle deal with Valve to give you some free Steam titles due to be released: HL2:Episode 2, Portal and Team Fortress.

The 2900XT is priced at around US$399.00.

ATI is looking a bit better in the low to midrange market, with the 2600 and 2400 series of cards sipping power and providing some good performance, although we have yet to see these cards benchmarked and on the market. Consumers will actually have to wait till around July for the 2600 and 2400 to hit store shelves.

From a pure performance perspective, Enthusiast gamers will go for the 8800GTX when Frames per second is king. Those people looking to watch their pockets and who view HD content on their PCs may opt for the ATI solution as they weigh the noise factor and power supply issues.

AMD- AMD Cuts X2 Processor Prices

Filed under: AMD, PC — Ramajay @ 6:39 am

Ahead of Intel’s price cuts on their Core2Duo processors, AMD has cut prices on X2 chips:

“AMD’s flagship Athlon 64 X2 line, meanwhile, received significant cuts. The price of the 6000+ was cut by 48 percent, while the 5600+, now priced at $188, was lowered by 42 percent. The AMD 5400+ was removed from the price list, while the price of the 5200+ dropped from $232 to $178, a more modest 23 percent decrease. Cuts were made down to the slowest 3600+ part, which was reduced in price from $102 to $73. AMD also trimmed the prices of its older Athlon 64 chips, which previously ranged from $102 for an AMD 4000+ part to $78 for the AMD Athlon 64 3200+. Today, those prices now range from $94 to $58. Slight cuts were made to the Sempron line as well.”

The prices for Turion processors remained unchanged.

Notebooks – Intel Core 2 Duo vs AMD’s Turion 64 X2

Filed under: AMD, Intel, Notebooks — Ramajay @ 7:46 am

notebook-cpu-comparison-charts.gifThe Intel Core 2 outperforms the AMD chip by a wide margin.

Intel’s Core processor family is rather dominant, and clearly offers better performance than the Turion 64 X2 family. If performance is what you’re looking for, AMD’s Turion 64 X2 is hardly an alternative. However, performance depends very much on a mobile computer’s particular configuration: memory size and speed, hard drive spindle speed and the graphics subsystem (discrete vs. shared graphics) have quite an impact on the result. Last but not least, keep processor performance in perspective: weight and battery runtime may be even more important to you anyway. In the end, we consider it very important to compare complete notebooks (and their costs) rather than focusing on CPU performance too much.”

For performance, the Intel line is the way to go at the moment for notebooks (and desktops too actually).

The Turion X2 56 is about US$263.00
The cheapest Core Duo , the T2300 isĀ  US$241.00 and the T2500 is US$294.00.

You can see for yourself how the performance numbersĀ  scale with the price, and it would be difficult to find a reason to purchase the AMD Turion processor, as the T2300 is cheaper and faster. Of course, overall notebook performance does depend on several factors however you would be hard pressed to find an AMD based notebook with a configuration that you could not match with an Intel processor.
