Calxeda has 5 watt web server based on the EnergyCore ECX-1000 1.1GHz processor. Compared to Intel’s 3.3GHz Xeon E3-1240, the results were surprising according to ZDNet.
This makes the Calxeda SOC (Server on a chip) ARM hardware 15 times more power-efficient that Intel’s hardware. According to Calxeda, this translates into a 77 percent reduction of overall total cost of ownership over three years.
And CPU performance is quite acceptable.
While the EnergyCore ECX-1000 is not as powerful as the Xeon E3-1240 — with it only able to handle 5,500 requests per second compared to 6,950 for the Intel hardware — it manages this performance while consuming a little over 5 watts, compared to over 100 watts for the Intel processor.
Multiply a thousand times, you see the potential savings.
I upgraded my desktop to the AMD Phenom II X4 620 chip in January for just $99. Today, AMD released a six-core processor starting at $199. From ZDNet:
AMD released today its first six-core processors for desktops, only a few weeks after Intel released its first six-core desktop chip. Unlike Intel’s “Gulftown,” which is available in limited quantities and costs more than $1,000 in retail, AMD’s “Thuban” processors start at around $200. AMD claims computer makers should be able to build complete desktops with Phenom II X6 chips for about the same price as the Core i7-980X Extreme alone.
The two new processors are the 2.8GHz Phenom II X6 1055T, which costs $199, and the 3.2GHz Phenom II X6 1090T Black Edition, which is $295. (With the Black Edition processors, you can overclock not only the CPU, but also other parts of the system, to further boost performance.) In addition to the six-core processor, this new high-end platform includes a supporting chipset, the 890GX, and Radeon HD 5000 series DirectX 11 GPUs. AMD refers to this platform as Leo. The Phenom II X6 can also be used as a drop-in upgrade in any AM2+ or AM3 motherboard.
If you are looking to upgrade soon, consider AMD’s Thuban processors. They can be used with your existing AM2+ or AM3 motherboard. Excellent value for the price.
Intel just came out with its latest Atom processor for the popular netbooks, the Atom N450 which comes with it’s own built-in graphics processor. In addition, the power consumption for these processors are down by 20 percent, operating at only 5.5 watts in idle mode. These processors will power the next generation of netbooks. Not only will the latest Atom be good for the environment, it will also be good for design, that’s one less chip to deal with. Netbooks will most likely continue to sell. Sales is up this year at a whopping 264%.
