FEATURES EXPLAINED
Intel
Core i5-4210U
The Intel Core i5-4210U is
an ULV (ultra low voltage) dual-core processor for ultrabooks launched in Q2
2014. It is based on the Haswell architecture and is manufactured in 22nm. Due
to Hyper-Threading, the two cores can handle up to four threads in parallel,
leading to better utilization of the CPU. Each core offers a base speed of 1.7
GHz, but can dynamically increase clock rates with Turbo Boost up to 2.7 GHz
for 1 active core or 2.4 GHz for 2 active cores. That's exactly 100 MHz more
than the i5-4200U.
Architecture
Haswell is the successor to
the Ivy Bridge architecture with improvements on both GPU and CPU performance.
The CPUs are produced in 22nm and offer an optimized branch prediction as well
as additional execution ports, improving performance per clock by almost 10 percent.
Furthermore, new features like AVX2 and FMA should increase the performance in
future applications.
Performance
The performance of the Core
i5-4210U is similar to the old and slightly higher clocked Core i5-3427U.
However, when using new instruction sets such as AVX2 the performance can be
significantly better. Thus, the CPU has sufficient power for office and
multimedia purposes as well as more demanding applications.
Integrated
Intel HD 4400 Graphics
The integrated HD Graphics
4400 offers 20 Execution Units (EUs) clocked at 200 - 1000 MHz with Turbo
Boost, making it somewhat faster than the former HD Graphics 4000 at similar
clock speeds. However, the HD 4400 is slightly slower than the HD 5000 found on
a number of other ULV models.
Power
Consumption
The i5-4210U is rated at a
TDP of 15 W including the graphics card, memory controller, VRMs and the
integrated chipset. Therefore, the CPU is suited for small ultrabooks 11-inches
or greater
NVIDIA
GeForce 840M
The NVIDIA GeForce
840M is a mid-range DirectX 11-compatible graphics card for laptops
unveiled in March 2014. It is one of the first cards based on Nvidia's new
Maxwell architecture (GM108 chip), but is still manufactured in 28 nm. The 840M
offers 384 shader units clocked at 1029 MHz (+ Boost) as well as 2 GB of DDR3
memory (64 bit, 2000 MHz effective).
Architecture
Compared to Kepler, Maxwell
has been optimized in several details to increase power efficiency. Smaller
Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an
optimized scheduler should lead to better utilization of the
shaders. Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90
percent of the performance of a Kepler SMX with 192 ALUs. GM108 features 3
SMMs and thus 384 shader cores, 24 TMUs and 8 ROPs (64-bit interface).
Another optimization is the
massively enlarged L2 cache. The larger size can process some of the memory
traffic to allow for a relatively narrow memory interface without significantly
reducing performance.
Similar to Fermi and Kepler,
the GM107/GM108 support DirectX 11.2 with feature level 11.0 only.
Performance
According to our benchmarks,
the GeForce 840M is about 30 percent faster than the old GT 740M and
just slightly behind a GeForce GT 750M (DDR3 version). Many
games of 2013/2014 can be played fluently in WXGA resolution (1366 x 768) and
medium or high detail settings. However, very demanding games such as Crysis 3
or Battlefield 4 will require lower resolutions and/or details.
Features
GM108 integrates the sixth
generation of the PureVideo HD video engine (VP6), offering a better decoding
performance for H.264 and MPEG-2 videos. Of course, VP6 supports all features
of previous generations (4K support, PIP, video encoding via NVENC
API). Unfortunately, HDMI 2.0 is still not supported.
