AMD ultra-low power APUs with "Jaguar" core are a few month away, but before they launch, the company is planning to release two Accelerated Processing Units, based on older Bobcat architecture. AMD E1-1500 and E2-2000 products are going to replace E1-1200 and E2-1800 parts, and they will offer slightly higher performance in graphics and numerical applications. Specifications of E1-1500 and E2-2000 APUs recently appeared on German version of AMD's website:
The E1-1500 and E2-2000 processors have 2 CPU cores with 1 MB L2 cache, Unified Video Decoder 3, and integrated HD 7000 series GPU with 80 shader units, that supports DirectX 11. Both APUs work with DDR3-1066 memory, and fit into 18 Watt thermal envelope. The difference between E1 and E2 chips is that the E2-2000 has higher CPU and GPU frequencies, and it extends memory support to DDR3-1333 memory.
AMD E1-1500 has CPU clocked at 1.48 GHz, and GPU clocked at 529 MHz. These numbers are about 6% higher than CPU and GPU frequencies of the E1-1200 processor.
While the E1-1500 will provide up to 6% better performance than its predecessor, the E2-2000 will have at most 3% better performance than the E2-1800. The E2-2000 APU has its clock speed boosted by 50 MHz to 1.75 GHz, whereas its maximum graphics frequency was increased from 680 MHz to 700 MHz. AMD specifications page doesn't show GPU stock frequency, however earlier reports indicated that it was raised to 538 MHz.
The table below contains the summary of processors' specifications. Upcoming APUs are in bold:
|E1-1200||2||1.4 GHz||1 MB||HD 7310||500 MHz||DDR3-1066||18 Watt|
|E1-1500||2||1.48 GHz||1 MB||529 MHz||DDR3-1066||18 Watt|
|E2-1800||2||1.7 GHz||1 MB||HD 7340||523 / 680 MHz||DDR3-1333||18 Watt|
|E2-2000||2||1.75 GHz||1 MB||HD 7340||538 / 700 MHz||DDR3-1333||18 Watt|
Update (Jan 7, 2013): The processors have now appeared on English version of the AMD website.
