AMD’s just revealed its quad-core Opteron chips manufactured with its new 45nm process. Based on the “Barcelona” chipset, the new “Shanghai” chips have a few extra tweaks: the L3 cache has risen from 2 to 6MB, giving it about 35% boosted power performance over the previous generation. The new chips also have better power management, meaning they can draw up to 35% less power under idle conditions, are compatible with DDR2-800 memory for faster memory accessing, and are backwards compatible with existing Socket-1207 mounting. These 75W server chips are out now, between 2.3 and 2.7 GHz clock speeds, and a desktop variety, dubbed “Dragon” is due early 2009. [AMD and PCWatch]
At CeBit today AMD finally showed off the fruits of its 45nm labors—one server and one desktop chip, a far cry from the 16 Intel launched with Penryn’s debut back in January. But, given AMD’s woes lately, on the technical and biznass fronts, we’re just glad to see ‘em.
The chaps over at Hot Hardware have put the Intel Core 2 Duo E8500 processor, which belongs to the (45nm) Wolfdale line, through its paces, and they sure were impressed. From their extensive testing, the processor, intended for desktop machines and ideal for gaming especially, did not seem to make any massive changes on an architectural level, however, small adjustments had a great overall effect on performance. The 6MB of L2 cache brought an impressive speed boost, while the power consumption and heat production levels both fell.
