Thread: Technology review

Nehalem seems to be the greatest change in architecture after the Pentium Pro. The previous generation had no defects so Intel needed some real advanced technology for this core.

Nehalem is made on the same manufacturing process just like the present generation, 45nm. It sports 2, 4, and 8 cores. The quad core version has 731 million transistors. The standard die is native quad core, meaning a dual core has two cores deactivated and the octacore is 2 dies together. Which is normal for an Intel CPU.

The CPU has 32 KB L1 instruction and 32 KB L1 data cache per core. Here’s the 256KB per core for L2 cache, and 2-3 MB per core for L3 cache. Which is a bi low as per the Intel standerd, but here we are not talking about the usual cores, and also more cache will only make the CPU huge.

Intel re-introduced a hyper-threading kind of technology. It is said to be refreshed and shows a performance increase compared to Hyper-threading which is quiet visible. It’s great CPU and there are a lot of features yet to cover.
