Seven months have passed since Intel officially launched its Core i7 processors, and for seven months they have remained at the top of our performance charts. Albeit pricey, Nehalem can’t be beat; it is the world’s fastest desktop microprocessor.

Just last week we previewed Intel’s upcoming more mainstream Nehalem, codenamed Lynnfield. Based on our early results and leaked Intel roadmaps, I’m expecting Lynnfield to pretty much negate the need for low end LGA-1366 Core i7 parts. Rather than allow Lynnfield to cannibalize Intel’s high-end LGA-1366 Core i7 platform, Intel is raising the performance bar with two new i7 CPUs: the Core i7 975 Extreme and the Core i7 950.

Processor Clock Speed Cores / Threads Maximum Single Core Turbo Frequency TDP Price
Intel Core i7-975 Extreme 3.33GHz 4 / 8 3.60GHz 130W $999
Intel Core i7-965 Extreme 3.20GHz 4 / 8 3.46GHz 130W $999
Intel Core i7-950 3.06GHz 4 / 8 3.33GHz 130W $562
Intel Core i7-940 2.93GHz 4 / 8 3.20GHz 130W $562
Intel Lynnfield 2.93GHz 2.93GHz 4 / 8 3.60GHz 95W $562
Intel Core i7-920 2.66GHz 4 / 8 2.93GHz 130W $284
Intel Lynnfield 2.80GHz 2.80GHz 4 / 8 3.46GHz 95W $284
Intel Lynnfield 2.66GHz 2.66GHz 4 / 4 3.20GHz 95W $196

 

The 975 replaces the 965 and is priced at $999 while the 950 replaces the i7-940 and is priced at $562. The chips run at 3.33GHz and 3.06GHz, respectively, with maximum turbo frequencies topping out at 3.6GHz and 3.33GHz. Intel really has no other external motivation to push for higher frequency parts, so we only see a bare minimum increase in specs here.

The Core i7 Extreme part, like its predecessor, ships unlocked so you can easily overclock it. Its un-core (L3 cache + memory controller) operates at 2.66GHz, just like the i7-965. The i7-950 is locked and runs its uncore at 2.13GHz, just like all other non-Extreme i7s.

Both of these chips use Intel’s new D0 stepping so they should clock up a bit higher than the original i7s.

    As weird as it seems TA152H is actually an i7 platform Fanboy! Reply

    Yeah: he's on crack. Reply

    I was asking because I want the flexibility of Crossfire and SLI on the same motherboard, which is something the Lynnfield/P55 platform will not provide. I'm worried that Intel will phase out the 920's, and I'll be left having to a $600ish cpu to get into the X58 platform. Reply
