Sandy Bridge is the evolutionary successor of the Arrandale architecture. Compared to the slower i7-2617M, the 2637M offers a higher clock speed (processor core and turbo, graphics turbo). Due to HyperThreading, the i7-2637M is able to handle 4 threads in parallel. However, this depends on the cooling and power consumption of the laptop. The base frequency of 1.7 GHz is relatively low, but due to Turbo Boost 2.0, the CPU may clock up to 2.8 GHz (on core loaded, 2.5 GHz with both cores loaded).
The Intel Core i7-2637M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. Intel Core i7-2637M ► remove from comparison 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). The performance of the Core i7-2630QM should be about 10-15% faster than a similar clocked Clarksfield Core i7 (see first tests by Anandtech). Therefore, the 2630QM should be on a level (or even faster) than a Core i7-920XM Quad-Core. In the 2630QM it is clocked from 650-1100MHz (Turbo Boost).įurthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part. 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). 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.ĭer 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. The 35W TDP rating includes the integrated GPU and memory controller.Sandy Bridge is the evolutionary successor of the Arrandale architecture. Looking at benchmarks of slower clocked Core i5 CPUs, the i5-2450M should position itself slightly above the old Core i5-620M and is therefore suited even for demanding tasks.
In the 2435M it is clocked with 650 or 1300MHz (with Turbo Boost).įurthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part.ĭue to the improved architecture and the new Turbo Boost 2.0, the average performance of the Core i5-2450M is higher than a similar clocked Arrandale Core i5. The i5-2450M offers an integrated graphics card ( Intel HD Graphics 3000) which is clearly faster then the older Intel HD Graphics in the Arrandale CPUs. The most noteable improvements is the improved Turbo Boost 2.0 and the integration of the graphics card into the 32nm CPU core. However, the integrated gpu offers a higher Turbo Boost clock rate. Compared to the 2510M, the 2450M does not support VT-d and Trusted Execution functions. The base clock speed is 2.5 GHz but due to Turbo Boost it can reach 2.8 GHz (2 cores active) and 3.1 GHz (1 core active). Compared to the faster Core i7, the i5 offers a smaller last level cache of 3MB. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 4 threads at once (for a better usage of the pipeline). The Intel Core i5-2450M is a fast dual core processor that first appeared in Dell laptops in 11/2011. Intel Core i5-2450M ► remove from comparison The 35W TDP rating includes the integrated GPU and memory controller as well as the CPU itself.
Its performance in synthetic benchmarks should be similar to the old Core i5-560M for demanding workloads. GPU clock rates in the 2520M core can run from 650 MHz up to 1300 MHz with Turbo Boost.įurthermore, an improved dual-channel DDR3 memory controller is included and shared between the CPU and GPU.ĭue to the new architecture and updated Turbo Boost 2.0, the average performance of the Core i7-2540M is higher than a similarly clocked Arrandale Core i5.
The GPU shares the same fast 元 cache with the CPU cores by utilizing a new ring bus. The i5-2520M offers an integrated graphics card (Intel HD Graphics 3000) that is clearly faster than the older Intel HD Graphics in Arrandale CPUs. The most notable improvements are the new 256-Bit AVX instructions, updated Turbo Boost 2.0, and the integration of a GPU onto the same 32 nm die.
