Intel Core i7-2760QM vs Intel Core i7-2670QM

Intel Core i7-2760QM

► remove Intel 2760QM

The Intel Core i7-2760QM is a fast high-end quad core processor for laptops and successor of the slower clocked Core i7-2720QM. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 8 threads at once (for a better usage of the pipeline). Compared to the previous Clarksdale quad-cores, the i7-2760QM is now manufactured in 32nm and offers an integrated graphics card and AES functions. Compared to the 2820QM, the 2760QM offers less level 3 cache (6 vs. 8MB) but should make this up due to the higher clock speed.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 256Bit AVX instructions, the improved Turbo Boost and the integration of the graphics card into the 32nm CPU core. Furthermore, the integrated memory controller was improved and supports up to 8 GB DDR3-1333.

The i7-2760QM offers an integrated graphics card (Intel HD Graphics 3000) which proved to be clearly faster than the old Intel HD Graphics in the Arrandale CPUs and on a level with entry level dedicated graphics cards like the GeForce 310M. The HD Graphics 3000 also supports Turbo Boost and clocks between 650 MHz and 1300 MHz in the i7-2720QM (should be similar to the 2760QM). As the graphics card shares the fast last level cache, the processor is a bit slower with activated GPU.

The performance of the Core i7-2760QM is only slightly below the Core i7-2920XM (see benchmarks below). Therefore, the performance should be sufficient for modern 3D games and demanding applications. Thanks to the fast Turbo Boost 2.0 even single threaded applications run very fast.

The relative high TDP rating of the 2760QM of 45 Watt enables the usage of the quad core only in 15" laptops and up. However, compared to the previous generation of quad-cores, the TDP improved, as the integrated GPU is now included.

Intel Core i7-2670QM

► remove Intel 2670QM

The Intel Core i7-2670QM is a fast quad core processor for laptops and successor to the popular i7-2630QM. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 8 threads at once (for a better usage of the pipeline). Compared to the 2630QM, the 2670QM offers higher base and turbo frequencies by 200MHz. Compared to the faster Core i7, the 2670QM does not feature the Trusted Execution and the VT-d functions.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 265Bit AVX instructions, the improved Turbo 2.0 and the integration of the graphics card into the 32nm CPU core. 

Der i7-2630QM offers an integrated graphics card (Intel HD Graphics 3000) which is clearly faster then the older Intel HD Graphics in the Arrandale CPUs. As the new GPU is included in the CPU, it is also manufactured in 32nm and shares the fast level 3 cache with the CPU cores (using a new ring bus). In the 2670QM it is clocked from  650-1100MHz (Turbo Boost). The Core i7-2675QM in comparison offers a higher Turbo Boost frequency of 1200MHz for the GPU part.

Furthermore, an improved (compared to Clarkdale) dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part.

The performance of the Core i7-2670QM should be only slightly slower than the old Core i7-2720QM that offers only a slightly higher Turbo Boost frequencies. Therefore, even demanding applications and games should run without performance problems.

The quad core CPU is still rated at 45 Watt TDP but now the integrated graphics card is also included (compared to the old Clarksfield Quad Core processors).
