AMD Introduces a new CPU/GPU for mainstream

By | April 30th, 2009



AMD has recently introduced ATI Radeon HD 4770, one of the best mainstream graphics card. It offers solid performance in sub $100 category, and should give comparative performance with High-End cards. Along with this, AMD also launched a $70 Athlon 7850 X2 Black Edition, which gives enough performance to drive High-End gaming and other processing needs. Let’s discover how good these two fare.

After releasing Radeon 4890 recently, AMD/ATI has come up with this new Radeon 4770 40nm based card for mainstream market, and takes the price/performance crown from Nvidia in this category. It’s actually a much updated version of Radeon 4670, which also was a success in this market category. The card uses GDDR5 memory running at 800 MHz (3200 MHz total) giving a whooping 51.2 GB/s bandwidth, something which the old 4670 lacked. Let’s look at its specifications and the complete line.
