Intel Core i7-2760QM
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.

NVIDIA GeForce GT 540M
The NVIDIA GeForce GT 540M is a fast middle class graphics card for
laptops. It is based on the same chip as the GeForce GT 435M but with
slightly higher clock speeds. Furthermore, it supports GDDR5 and
900MHz DDR3 graphics memory. Unfortunately, no models have utilized
GDDR5 due to the increase in power consumption and higher prices
compared to DDR3 VRAM.
GF108 Architecture
The GT 540M is based on the same GF108 architecture as the older GT
435M. The GF108 stems from the GF100 (Fermi) DirectX 10 architecture.
However, it is optimized for the consumer end (gaming) and stripped
down to save power. More information on the architecture can be found
on our GeForce GT 435M page.
Performance
In general, the performance of the 540M lies between the Radeon HD
5650 and 5730 in our first benchmark tests. Therefore, the 540M is
about 10% faster than the GT 435M using DDR3 graphics memory.
Paired with a fast CPU, demanding games of 2010 should run fluently in
medium to high details and SXGA (1280x1024) resolution. In our tests,
for example, Call of Duty: Black Ops and StarCraft 2 ran fluently in
high details and 1360x768. More gaming benchmarks can be found below.
Demanding games released in 2011 like Anno 2070 or Skyrim will only
run fluent in low to medium detail settings.
Features
A novelty of the GF104/106/108 chips is the support for Bitstream HD
Audio (Blu-Ray) output via HDMI. Alike the Radeon HD 5730, the GT 540M
can transfer Dolby True HD and DTS-HD bitstream without quality loss
to a HiFi receiver.
The GT 540M offers PureVideo HD technology for video decoding using
the GPU. The integrated Video Processor 4 (VP4) supports feature set C
and therefore the GPU is able to fully decode MPEG-1, MPEG-2, MPEG-4
Part 2 (MPEG-4 ASP - e.g., DivX or Xvid), VC-1/WMV9, and H.264 (VLD,
IDCT, Motion Compensation, and Deblocking). Furthermore, the GPU is
able to decode two 1080p streams simultaneously (e.g. for Blu-Ray
Picture-in-Picture).
Through CUDA, OpenCL and DirectCompute 2.1 support, the GeForce GT
540M can be of help in general calculations. For example, the stream
processor can encode videos considerably faster than can a modern
CPU. Furthermore, physics calculations can be done by the GPU using
PhysX (supported by Mafia 2 and Metro 2033). However, the GPU is not
fast enough to calculate PhysX high detail game settings.
Following the current 3D trend, the 540M supports 3D Vision. It
enables the laptop to send 3D content (3D games, 3D Web Streaming, 3D
photos, 3D Blu-Rays) to a built-in 3D-enabled screen or an external 3D
TV if supported by the manufacturer. This feature is disabled if the
notebook includes Optimus.
The power consumption of the GeForce GT 540M should be similar to the
GeForce GT 435M or Radeon HD 5730 and is therefore suited for 15" or
larger laptops. Without load, the chip is clocked approximately at
50/101/137 MHz (chip/shader/memory) in 2D mode and 202/405/324 in 3D
mode to save power. Furthermore, the 500M series supports Optimus to
automatically switch between the integrated graphics card from Intel
and the Nvidia GPU. The implementation of the Nvidia graphics
switching technology is dependent on the laptop manufacturer.
