We first encountered the Core i5-2520M (2x2.5 GHz) in the Vaio SB1 pre-production device. The turbo clocking is at 3.2 GHz, but can go even further with the Turbo 2.0 depending on the temperature (loading on a core, not 4 x > 3.2 GHz). The 2011er cores can raise the Turbo standard via "Dynamic Range @ Turbo Frequency Limits", so long as the cooling keeps it within the temperature limits. hp pavilion dv9000 battery

The HD Graphics 3000 graphics chip in the processor (650-1300MHz) is combined with a Nvidia Geforce GT 520M. compaq presario cq60 batteryThe automatic Nvidia Optimus GPU switching deactivates the GT 520M when not in use. The maximum energy use of the CPU (TDP) is at 35 watts (CPU + HD 3000 + memory controller). hp compaq 6710b battery

The RAM capacity amounts to 4 GB. Two gigabytes are soldered, two gigabytes are stowed in the single RAM slot. The quiet Hitachi harddrive comprises a total of 320 GB. IBM thinkpad r60e battery

How fast is the new i5-2520M (2.5Ghz) compared to the 2010 i5-generation? Lenovo thinkpad r60 battery When computing with one core, it gets 5018 points (Cinebench R10 Single 64bit). A 2010er 460M (2.53 GHz, Turbo 2.8Ghz) comes out with 339 points (-22%) (ex. Acer Aspire 3820TG, 13.3"). An indication of Turbo Boost's impact are the 4870 points (-3%), which achieved the same 2520M-CPU in the Vaio SB1 Lenovo thinkpad t60 battery .

Those who encode videos will profit from Multi-Threading with a higher clock rate. The i5-2520M (4 threads) gets 10161 points (Cinebench R10 multi 64bit). The 2010er i5-460M (4 threads) clearly looses: 8060 to 8342 points (ex.: Acer Aspire 5820TG). Lenovo thinkpad x60 battery

The PCMark Vantage ended with 7031 points. That's quite a lot. Previously, most i5-460M-systems (same standard clock rate) got up to 6000 points Acer Aspire 3820TG-5464G75nks, so long as they were also equipped with HDD. Lenovo thinkpad t500 battery

While the HDD-sub score isn't particularly strong (3341 points), the Communications sub-score certainly is: 9291. Reason: The i5-2520M on our tester has the business functions Intel VT-d, Trusted Execution Technology and AES New Instructions (encryption). Lenovo thinkpad t61 battery

The hard drive from the manufacturer Hitachi reads with 59 MB/s in the Sequential Read. The values of the Crystal Disk Mark generally always come out somewhat higher. Only fast 7,200 rpm hard drives get around 75 or 90 MB/s here. SSDs play in a whole different league (reading sequentially: from 150 MB/s and up). Lenovo thinkpad r61 battery

The Nvidia GeForce GT 520M (1024 MB DDR3) is the weakest dedicated graphics card of the GeForce GT 500 series. It's based on the GT119 core with a 64 bit connection to the graphics memory (usual: 128 bit). Lenovo thinkpad t400 battery

The performance of the DirectX-11 GPU is slightly higher than the HD Graphics 3000, Lenovo thinkpad t410 battery which is integrated into the i5-CPU (Optimus). As the driver support from Nvidia is better, one can still expect noticeably better gaming performance from the GT 520M. The 3DMark2006 resulted in 4736 points against 3941 points (GT 520M / HD 3000). In the 3DMark Vantage, the Geforce computes 14% faster than the HD graphics. Lenovo x300 battery

Compared to the current AMD entry-level GPU HD 6470M (-10%), Lenovo 3000 v100 battery the GT 520M appears to have an advantage in the 3DMark06. But our test games show an identical performance with medium details. With higher details, the HD 6470M (-5%) is at a disadvantage, though these resolutions are still not enough for fluid gaming.

Current games shouldn't be on the wish lists of Samsung QX412 users. At best, these could only be played when DirectX11 details are turned off and with the lowest details and resolutions.Lenovo 3000 v200 battery

Older games like Left 4 Dead,Lenovo 3000 c200 battery Trackmania Nations or World in Conflict are, however, playable in high and, where applicable, medium details. The difference in performance between the HD 3000 (IGP) and GT 520 was around approximately 20% in StarCraft 2, which answers the question of the GPU's usefulness. As long as buyers ask for "any dedicated" graphics with Radeon or Nvidia labels, manufacturers will continue to build in these small GPU classes. Lenovo ideapad s10 battery

Samsung notebooks are often exemplary in terms of their noise. The QX412 also keeps this motto alive. The level remains remarkably low, especially if silent mode is activated. This function limits the processor's speed to 0.8 GHz and turns off Turbo-Boost. acer aspire 5920 battery
