Fine HD

You might not be a big graphics card PC buff, but in the under $US100 sector, the new ATI Radeon HD 5570 is definitely a product to know. Tom’s Hardware shares their excellent, extremely thorough review of the product here.

In September of 2008 – almost a year and a half ago – ATI surprised everyone on a budget with the launch of its Radeon HD 4670.

Released at $US80, the card was priced to fight the entry-level GeForce 9500 GT, and yet the 4670’s specifications were comparable to the previous-generation’s Radeon HD 3870 flagship.

To make a long story short, the Radeon HD 4670’s performance humiliated its competition. With 320 shader cores at its disposal, the Radeon HD 4670 changed the game at its price point. The card’s presence forced Nvidia to create the GeForce 9600 GSO from high-end parts that were more expensive to manufacture, also causing the company to drop the price of its GeForce 9600 GT.

Since its inception, the Radeon HD 4670 has remained one of the best budget gaming cards on the market (and a staple recommendation in our Best Graphics Cards For The Money column). It is also notable that it held the distinction of being the fastest reference card that didn’t require a dedicated PCIe power cable for over a year, until Nvidia introduced its GeForce GT 240, later bested by ATI’s Radeon HD 5670.

ATI truly raised the bar on what we now expect from an $US80 graphics card with its Radeon HD 4670. And it just so happens that today, AMD is releasing the spiritual successor to that venerable card in its Radeon HD 5570, also priced to compete at $US80.

With the Radeon HD 5450 too slow to provide enthusiast-class gaming performance on a budget, and the Radeon HD 5670 priced at $US100, we certainly can’t help but to have high hopes that this new card might be the Holy Grail; an offering able to deliver usable triple-monitor Eyefinity gaming performance on an entry-level budget.

Radeon HD 5570 Architecture
In the conclusion of the Radeon HD 5670 review I wrote last month, I mentioned that I hoped the Radeon 5500-series would include a DDR3-based version of the Radeon HD 5670. It looks like it’s my lucky day:

Yes, the new Radeon HD 5570 is a DDR3-equippped Radeon HD 5670 with a 125 MHz-lower core clock rate. If you look at the data rate, you can see that the Radeon HD 5570 offers less than half the memory bandwidth of the 5670. This is because DDR3 theoretically delivers half of the bandwidth that GDDR5 memory provides at the same clock speed and on the same memory bus. As a result, we can expect a significant difference in performance between these two closely-related cards.
