As you may know, Intels CEO has recently went on record that merom will launch in august. Perhaps a little late for it to be announced at the wwdc, but given apples preferential treatment, the macbook line should be updated soon after (late september, perhaps?). Meroms can be snapped onto existing motherboards, therefore although harware increment is insignificant, performance gain is not. Meroms have 4mb L2 cache (2ghz upwards), will cost the same as yonahs do presently, and offer other advancements such as 64-bit computing (yonahs only 32-bit). Benchmarks floating around the net suggest theyll be 25% faster and consume the same wattage as yonahs of same speed (in ghz). Its turning out to be a nifty little chip and it seems to be consensus around the forum that those that can wait, wait. at least until late june, when official benchmarks will be out and the picture will be clearer. NOW, concerning the Santa Rosa chipset that will replace Napa come Q2 2007. Thats also supposed to boast some pretty impressive gains. FSB will be bumped from 667 to 800, it will feature wifi spec "n" AND a much improved integrated graphics - 400mhz with 8 pipelines and support of shader model 4, as opposed to the current 250mhz, 4 pipes and sm2 support. Nonetheless, i find that Q2 2007 is too far away to wait for, as, by then, well probably have quad cores meroms (or its successor) on the horizon. Turns out this intel world isnt too shabby after all!
