Back to similarities: For the power calculation, the Ultrabook has a powerful processor Intel Core i7-3517U dual-core ULV (Ultra Low Voltage) with hyperthreading (4 tasks) and a frequency of 1.9 GHz. batterie chargeur Asus Eee PC 1008 Turbo Boost raises the frequency 3.0 Ghz or 2.8 Ghz with 2 hearts. During our test, the processor supports all levels and Turbo Boost Speed Step (energy savings) without problem. An advantage of the Core i7 Core i5 L3 cache is larger (3MB vs. 2 MB).batterie chargeur Asus X52J
For graphics, it has the right to Intel GMA HD 4000 , which supports DirectX11 and Shader 5.0. This GPU is not made to play, but it is enough for the office and videos. The UX21A has 4 GB DDR3 RAM , soldered to the motherboard, so not replaceable.batterie chargeur Asus Eee PC 1008HA

Processor
For the first test series, we used the testing tools in Maxon. The Intel Core i7-3517U UX21A reaches the 10,333 items in the test Multi Heart CineBench R10 (64-Bit) – which puts it in 3rd position in our top 100. The Samsung Series 9 900X3C-A04DE (same CPU) is 10,207 points. The Zenbook UX21E CPU with an Intel Core i5-2467M dual-core is 7158 points in the same test (a difference of 31%). batterie chargeur Asus G53JW Manufacturers often use the less powerful Intel Core i5-3317U for their system. The CPU (part of the generation Ivy Bridge) is often found on Ultrabooks input range. Mean score: 8712 – 15.7% less. But where is the same CPU with the Acer Aspire V5-171-53314G50ass and HP Envy Spectre Ultrabook XT 13-2000eg .batterie chargeur Asus G70s
CineBench R11.5 confirm these measures . Compared with UX21A, the UX21E with its Sandy Bridge CPU is behind: 2.76 point and 1.93 for the last points for the previous – a difference of 30%. The Intel Core i5-3317U is a bit better – 2.3 points – but still behind the i7 dual-core UX21A (17% difference).batterie chargeur Asus U30JC-A2B

System performance
overall performance is more than adequate. Because the loading time of the SSD are fast and without delay . PCMark 7 confirms our impressions: the score of 4089 dots placed 3rd in our top 100. Samsung 900X3C-A04DE is slightly better, batterie chargeur Asus F3Jc although we do not see too much difference to the naked eye. The predecessor of our test laptop is back: 3488 points – a difference of 15%. The Windows performance index expressed quite simply.batterie chargeur Asus N71JV

We had a Solid State Drive (SSD) from SanDisk with 128 GB model (type U100 ) is placed on a circuit owner. The SSD supports SATA III with a theoretical speed of 6 Gbit / s. CrystalDiskMark shows excellent speed of 440 MB / s (read) and 270 MB / s (write) , although there was some slowdowns fleeting (4k: 14/10 MB / s). Access times are on par with the competition (AS SSD). there are some that are better mSATA SSD – the LiteOn LMT 256M3M Samsung 900X3C-A04DE is a good example.Asus A42-M70
Asus is venur – like other manufacturers – components from multiple vendors. It is therefore possible to receive a Ultrabook with a hard drive from A-Data (in any case according to the forums). It is best according to the benchmarks here and also visible in this video . But the difference is invisible in everyday usebatterie chargeur Asus K40C.

GPU performance
We took a look at the Intel GMA HD 4000 with benchmarks from Futuremark. In 3DMark 06 , the CPU is rated 4893 point in 1280×1024 resolution – a pretty average score. Other models such as ultra-thin Toshiba Satellite Z930 and the HP Envy 13 Spectre Ultrabook XT offer comparable performance. The Asus Zenbook UX21E (with an Intel GMA HD 3000) but 16% slower (3622 points). The Apple MacBook 11 Mid 2012 running Windows 7 (Boot Camp) has the same score as our model. Performance are not huge – but the video playback Full HD is never a problem.batterie chargeur Asus X72JR
