New 90nm Sempron Socket 754 processors already selling

Intel price lists: Xeon 2MB L2, global price cut

New 90nm Sempron Socket 754 processors already selling

Simultaneously with the price cut AMD expanded its processor list with new Semprons that replaced older value products. In Japan they already sell these novelties, including new Sempron 2600+, 2800+ and 3000+:

According to AMD processor roadmap (as the company haven´t disclosed anything about the new CPUs), these Semprons are based on 90nm Palermo core with SOI. Well, the value 90nm processors are not that hot news, as already last month they started selling 90nm Sempron 3100+ (SDA3100AIO3BA) and LV Mobile Sempron 2600+ (as for Mobile Sempron 2600+, 2800+ and 3000+, the official website states they are also based on 90nm process — the Georgetown core).

The new Semprons are encased into usual 754-pin mPGA packages implying the built-in single-channel memory controller. See the table below for model names and specs.

Desktop Semprons Clock rate L2 OPN
Sempron 3100+ 1.8GHz 256KB SDA3100AIO3BA
Sempron 3000+ 1.8GHz 128KB SDA3000AIO2BA
Sempron 2800+ 1.6GHz 256KB SDA2800AIO3BA
Sempron 2600+ 1.6GHz 128KB SDA2600AIO2BA

You can see that L2 cache differs as well as the clock rate ("BA" suffix speaks of 90nm process, while the preceding "2" or "3" means 128 or 256 KB L2). It´s interesting that 128KB L2 processors were packed just about a month ago unlike the 256KB L2 ones:

The transition to the new Palermo core (D0 stepping) doesn´t imply the addition of any fundmentally new features, but the 90nm process reduces the chip size which, in turn, reduces the cost price and allows to make faster CPUs in the future.

Intel price lists: Xeon 2MB L2, global price cut

Early this week Intel expanded its Xeon server series for one- and two-way configurations. The new Xeons based on the N0 stepping (Irwindale, CPUID = 0F43h) don´t differ much from the previous E0 stepping (Nocona): actually it´s just the L2 that was doubled (2MB now). Therefore all the innovations of earlier steppings (EM64T, XD-Bit, Thermal Monitor 2, C1E, DBS, SSE3, Hyper-Threading, etc.) are present in the novelties as well.

The increased amount of transistors in Irwindale core (plus additional 1MB L2) resulted in up to 18% performance boost in certain applications comparing to Nocona-based solutions, according to Intel. Still it negatively affected the energy consumption: at the same 90nm process, and 800MHz bus, N0 Xeons consume 110W instead of 103W (E0). The new processors are packed into usual 604-pin PPGA packages. The pricing policy is as follows:

CPU Price for 1,000 units
Xeon 3.6 GHz $851
Xeon 3.4 GHz $690
Xeon 3.2 GHz $455
Xeon 3.0 GHz $316
    * sSpec is available here

In Japan they already showcase two-way systems on the new 3.4 GHz Xeon processors, which normally operate on Supermicro X6DAE-G2 motherboard (E7525 chipset; Irwindale is also claimed to work with E7320 and E7520).

Japanese version of SiSoftware Sandra still makes mistakes determining Irwindale specs (e.g. the core name), but 2MB L2 are clearly visble:

The list of vendors which are going to ship systems on the new Xeon processors includes IBM, NEC, HP, and 14 smaller companies, including Hitachi and Fujitsu. For sale novelties will be available (in Japan) early in March.

Besides the processors, Intel announced the Intel IOP333 I/O chip on Intel XScale architecture. The novelty allows to build RAID 6 storage systems. The company also mentioned the new Xeon MP processors (Potomac core with 8MB L3 and entry-level Cranford core with 2MB L2) to be introduced within three months.
