Intel Core 2 Duo (Conroe) E6400 and E6700:
Brief Characteristics of Intel Core 2 Duo Processors
The architecture of Intel Core 2, represented by the desktop core Conroe, has grown from the mobile core Yonah. Which in its turn stems from the ideas of Pentium M (Banias and Dothan). What concerns the latter, it has been noted many times that they are direct descendants of the 6-gen core of Intel processors (P6), which had been designed prior to Pentium Pro and had lived to Pentium III. Thus, on one hand, Core 2 is a step back, as it sort of cancels many architectural solutions that appeared in processor cores of the later generations (the famous Intel NetBurst architecture of the seventh generation). On the other hand, we cannot say that Core 2 is the direct heir to Intel P6 because of too many modifications. The new core has been altered beyond recognition
.
The key differences of the new architecture from the closest parent — Intel Core Duo (Yonah) come down to the following:
Improved decoder, expanded to 4 decoders of x86 macro-ops (3 in the closest counterparts, Intel Pentium M / Core Duo).
The execution speed of 128-bit SIMD instructions is one instruction per cycle in each execution unit (twice as fast as Yonah).
Improved operations with memory and hardware prefetch.
L2 Cache is shared by both cores, its size is distributed dynamically depending on the load (we have already seen it in Intel Core Duo).
Better power saving technologies.
Support for a new set of SIMD instructions, SSE4.
The grapevine provides the following parameters of new processors:
65 nm process technology
1.87-2.93 GHz core
800-1066 MHz FSB (probably 1333 MHz in XE models)
2-4 MB Shared L2 Cache
65-80 Watt TDP
From the same sources not to be revealed here
, the Core 2 Duo line will be initially represented by the following models:
E4xxx series — a single E4200 CPU, 1.6 GHz, 800 MHz FSB, 2 MB Shared L2 Cache.
E6300/6400 processors— 1.86/2.13 GHz, 1066 MHz FSB, FSB, 2 MB Shared L2 Cache (note that our engineering sample of the E6400 has a 4MB L2 Cache!)
E6600/6700 processors — 2.4/2.66 GHz, 1066 MHz FSB, 4 MB L2 Cache.
X6800 processor (eXtreme Edition) — 2.93 GHz, 1066 MHz FSB, 4 MB L2 Cache.
"E" means TDP from 55W to 75W, "X" — above 75W. TDP indexes "T", "L", and "U" are reserved for mobile and Ultra Low Voltage processors of the Core 2 series. We have also heard that the 4xx0 and 6xx0 series will include desktop processors, while the 5xx0 and 7xx0 series — mobile models. Continued
