Notebook Processors In the following report we present all laptop processors which are available at the market at present and give a rough classification of the current consumption and the performance of the different architectures.
An approximate rating with average benchmark values can be found in our beta version benchmark list of mobile processors (coming soon).
Intel Core 2 Duo (Merom)
This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more current consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
Features are 2 cores, a 64-bit EM64T command amplification and 2 or 4 MB L2 Cache and 291 millions of transistors, which are finished in 65 nm. Furthermore all types support "Execute Disable Bit" technics, SSSE3 (SSE4), Enhanced Speedstep, LaGrande and most types the virtualisation technics (VT) Vanderpool.
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower tensions (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
The energy need of the processors is marked by pre-set letters in front of the type designation (number).
E ... 55-75 Watts
T ... 25-55 Watts (standard version in notebooks)
L ... 15-25 Watts (low boltage)
U ... <15>
The 4-digit sequence indicates the type series (first digit) and performance (other digits). The Core 2 mobile processors ought to get 5XXX and 7XXX (at present T2XXX for Core Duo and T1XXX for Core Solo).
Core 2 Duo was presented in 31. July 2006 with the following versions (versions with FSB 800 and Dat - dynamic acceleration technology in 05.09.07):

- T7100, 1.80 GHz, 2 MB L2 Cache, 800 MHZ FSB, VT, DAT
- T7200, 2.00 GHz, 4 MB L2 Cache, 667 MHZ FSB, VT - 34 Watts
- T7300, 2.00 GHz, 4 MB L2 Cache, 800 MHZ FSB, VT, DAT

- T7500, 2.20 GHZ, 4 MB L2 Cache, 800 MHz FSB, VT, DAT
- T7600, 2.33 GHz, 4 MB L2 Cache, 667 MHZ FSB, VT - 34 Watts
- T7600G - as T7600 but with free selectable multiplier (for overclocking)
- T7700, 2.40 GHz, 4 MB L2 Cache, 800 MHz FSB, VT, DAT
Intel Core Solo
Single core version of the Core Duo and successor of the Intel Pentium M; Because of the 65nm reduced structure width also smaller current consumption than Pentium M (maximally 27 Watts); the performance is comparable with the equivalent clocked Pentium M (somewhat faster because of a few improvements).
Models:
-T1200 mit 1.50 GHz, FSB 667 MHz, 2MB L2 Cache
-T1300 with 1,66 GHz 2MB L2 Cache
-T1350 with 1.86 GHz, FSB 533 MHz, 2MB L2 Cache (about the same level like Pentium M 750)
-T1400 mit 1.83 GHz, FSB 667 MHz, 2MB L2 Cache
Ultra low voltage models (maximum 5.5 Watt):
-U1300 mit 1.06 GHz, FSB 667 MHz, 2MB L2 Cache
-U1400 mit 1.20 GHz, FSB 667 MHz, 2MB L2 Cache
-U1500 mit 1.33 GHz, FSB 667 MHz, 2MB L2 Cache
Intel Pentium M
900 - 2260 MHz, 1-2 MB level 2 Cache, 90nm and 130nm production process, 400 and 533 MHz front Side bus (FSB);
It is also available as a low voltage version with very small current consumption.
