POSTER: computer news   ||   AMD 45 NM SHANGHAI OFFICIALLY PRESENTED

DATE:2008-11-13

AMD already promised to present the first 45 nm processors in the middle of November, and today this promise was materialized in the announcement of nine models shanghai, which work at frequencies from 2.3 to 2.7 GHz .

Those processors are released on 45 nm technology using immersion lithograph - Intel company , for example, produces its 45 nm processors on dry technology, and it is going to use immersion lithograph only within the 32 nm technical process.

The first shanghai processors are based on C2 stepping, they have 512 KB cache in the second level for each of four core, and the general cache in the third level with 6MB volume . Their predecessors was satisfied only by 2 MB cache in the third level. The hyperTransport frequency is limited to 1.0 GHz, models with faster bus hyperTransport 3.0 will be released only in the second quarter 2009.

Shanghai processors with higher frequencies will appear in the first quarter 2009, they will have the ACP value not less than 105 W, whereas current models are 75 W . In the first quarter AMD will also release shanghai processors with ACP value not more than 55 W.

It is important to note that the memory controller in shanghai processors supports dual-channel memory DDR 2-800, whereas 65 nm predecessors was satisfied only by DDR 2-667. Opteron processors with DDR- 3 support will be released only in 2010, and the socket F platform will continue to be developed - AMD plans in 2009 to present the six-core 45 nm processors Istanbul, which will be compatible with socket F.

AMD shanghai 45 nm price

Here is the list of shanghai processors Prices :

  • Opteron 8384 (2.7 GHz, ACP=75 W) - > $2149;
  • Opteron 8382 (2.6 GHz, ACP=75 W) - > $1865;
  • Opteron 8380 (2.5 GHz, ACP=75 W) - > $1514;
  • Opteron 8378 (2.4 GHz, ACP=75 W) - > $1165;
  • Opteron 2384 (2.7 GHz, ACP=75 W) - > $989;
  • Opteron 2382 (2.6 GHz, ACP=75 W) - > $873;
  • Opteron 2380 (2.5 GHz, ACP=75 W) - > $698;
  • Opteron 2378 (2.4 GHz, ACP=75 W) - > $523;
  • Opteron 2376 (2.3 GHz, ACP=75 W) - > $377.

The characteristics of processors are given below:

The default core supply voltage is equal to 1.35 v, the max case temperature lies within the limits from 55 to 77 degree Celsius. With 2.5 GHz frequencies the memory controller operates at 2.0 GHz frequency, in the frequencies range 2.6-2.7 GHz the memory controller frequency rises to 2.2 GHz.

AMD asserts that in comparison with 65 nm with Barcelona processors , the new 45 nm processors shanghai ensure up to 35% faster operation speed with lower energy consumption in the quiescent conditions - by the same 35%. In the opinion of independent sources, shanghai processors on average is up to 20-25% faster than their 65 nm predecessors.

We will not forget, that the contribution in this increase is also due to the increased by 200% cache volume in the third level, and also to the increased memory frequency (DDR 2-667 - > DDR 2-800).

Nehalem architecture has numerous optimization, capable of giving to it forces in the server segment, but such Intel processors will be released only in the following year.

The announcement periods of the 45 nm Deneb processors will be only in the first quarter 2009, and they will become a part of the new platform dragon. Besides the 45 nm processors phenom X4, this platform will unite the chipset AMD series 7xx and video card series radeon HD 4xxx.

In the press release the 45 nm desktop processors are mentioned by : Phenom II X4.
