This week AMD revealed prices of soon to be available socket AM1 Sempron processors. Socket AM1 is a new low-power platform, that combines "Kabini" systems on a chip in an upgradeable PGA package, and an inexpensive motherboard with the minimum amount of logic. The Fusion Controller Hub (FCH), responsible for interfacing between the APU and peripheral devices, on this platform is located on the processor. In theory, this allows owners of such socket AM1 boards to upgrade not only the CPU/GPU, but also the chipset. Although the socket AM1 platform was announced in January, AMD haven't disclosed model numbers and prices up until this week.
Currently, the official pricelist contains two socket AM1 processors: Sempron 2650 and Sempron 3850. The former is a dual-core chip with 1 MB of shared L2 cache, and 1.45 GHz clock speed. The accelerated unit has an on-chip HD 8000 series GPU with 128 shader cores, clocked at 400 MHz. The 2650 supports DDR3-1333 memory, and has 25 Watt TDP. The processor is priced at $31, which is a few dollars cheaper than anticipated.
The Sempron 3850 is $5 more expensive than the 2650, but it offers quite a few performance improvements for the price. The APU has twice as many cores and twice larger L2 cache. Its integrated graphics unit runs at 13% higher frequency. The processor supports DDR3-1600 memory. The only downside is lower 1.3 GHz speed, which allows it to fit into the same 25 Watt TDP power envelope.
It is expected that, in addition to Sempron line, AMD will also release Athlon 5150 and Athlon 5350. Both are quad-core processors, running at 1.6 GHz and 2.05 GHz respectively:
|Athlon 5150||4||1.6 GHz||2 MB||HD 8400||600 MHz||DDR3-1600||25W||$45|
|Athlon 5350||4||2.05 GHz||2 MB||HD 8400||600 MHz||DDR3-1600||25W||$54|
|Sempron 2650||2||1.45 GHz||1 MB||HD 8240||400 MHz||DDR3-1333||25W||$31|
|Sempron 3850||4||1.3 GHz||2 MB||HD 8280||450 MHz||DDR3-1600||25W||$36|
All socket AM1-compatible APUs will be officially available in a week, but they are already in stock in smaller US online stores.
