You can customise Optimus through the installed NVIDIA driver, and tell it which programs should use the Quadro graphics card and which ones should use integrated graphics. As soon as we disabled Optimus and then re-enabled it, the benchmark results were more along the lines of what we expected. When we initially ran our benchmarks with Optimus enabled in the BIOS, all of our benchmarks ran a lot slower than we expected (despite choosing the maximum power profile). We appeared to have some problems with graphics card's Optimus feature though. A full list of certified applications can be found on NVIDIA's Web site. It's designed to accelerate design and graphics applications such as AutoCAD, Photoshop and 3dsMAX. This shows that it has plenty of guts when it comes to processing real-time 3D graphics, but it's not designed for gaming. ![]() The ThinkPad W250's NVIDIA Quadro 1000M graphics adapter has 2GB of GDDR5 RAM and it recorded a score of 8299 in 3DMark06. You can order the ThinkPad with a 160GB Intel SSD instead, which will boost the performance of the laptop, eliminate drive noise, as well as slightly reduce its heat and weight - but you'll have to fork over an extra $480. The hard drive is mounted in rubber dampers and it's monitored by a motion sensor, which parks the heads when it detects excessive movement. This isn't the fastest rate we've seen from a single 7200rpm, 500GB drive, but anything over 30MBps is generally a good result in this test. In our hard drive transfer test, in which we copy 2.12GB worth of 2-50MB files from one location on the hard drive to another, the 7200rpm hard drive recorded a rate of 31.64 megabytes per second. This is 5min better than what the Dell achieved in the same test. Using AutoGordianKnot, our test DVD file was turned into a 1.45GB Xvid file in only 46min. However, the ThinkPad posted a much better time in our video transcoding test. It was only 1sec slower than the Dell in Blender and 2sec slower in iTunes. Both of these times are slower than the Dell Vostro 3550, which we're comparing here because it uses the same CPU, but this doesn't mean that the W520 is sluggish. It helped the laptop to a time of 38sec in our Blender 3D test (using four threads) and 46sec in our iTunes MP3 encoding test. ![]() The ThinkPad W520's Core i7-2620M runs at 2.7GHz, and it has two cores and Hyper-Threading. Changing power profiles didn't make things run quicker, but disabling and re-enabling Optimus graphics seemed to do the trick. Initially, this configuration didn't perform well at all in our tests and the machine delivered speeds that were under half what we expected. Refer to Pic-4.While the ThinkPad W520 is available in different configurations, we looked at the 428426M, which is kitted with a Second Generation Intel Core i7-2620M CPU, a Full HD (1920x1080) LED-backlit screen, NVIDIA Quadro 1000M graphics (with 2GB RAM and Optimus switching technology), 4GB of 1333MHz DDR3 SDRAM (it supports up to 16GB) and a 500GB, 3Gbps, 7200rpm hard drive. This configuration may also reduce system performance and raise system surface temperature. (The default setting from factory is "Optimized" which balances performance, noise, and temperature.) We suggest to select " Quiet" setting where cooling fan and processor speeds are lowered to reduce fan noise. It shows 4 thermal settings where you can select your preference.Launch " Dell Power Manager", and then click " Thermal Management" in left pane.After DPM Service is installed, open Windows Store application and search for " Dell Power Manager", and then click Get button to install.Click the OK button to continue to install the DPM Service. Note: If you have not previously installed "Dell Power Manager", the installation wizard informs you to install this.
