Before they unleash their Temash and Kabini platforms (more on that in a future post), AMD has released some small upgrades for their current-gen Brazos 2.0 platform. The new processors, the E1-1500 and E2-2000, are direct replacements to the existing E1-1200 and E2-1800, respectively. Compared to the E1-1200, the E1-1500 gets a speed boost of 80 MHz (1.48 GHz vs 1.4), which is hardly noticeable. The GPU also gets a small push of 29 MHz (529 MHz vs 500). You might notice this difference, but it's not enough to get you playing any new games. On the high end, the E2-2000's CPU is 50 MHz faster than its predecessor (1.75 GHz vs 1.7 GHz); again, insignificant. The GPU gets clocked up to 700 MHz over the previous 680 MHz. Both new processors retain the RAM speeds of the procs they replace (DDR3/1066 for E1-1500, DDR3/1333 for E2-2000).
On the whole, these new platform bumps are nothing to be excited about. If all other factors are the same, however, there's no reason to buy a netbook/laptop with the older processors. If you need a computer soon (i.e. you can't wait for the next generation), now's a good time.
