Hello Forum,
I made some extensive benchmarks in order to compare a ThinkPad W701 with a Quadro 2800M GPU, a ThinkPad X230 with an Intel HD 4000 GPU and a ThinkPad T520 with integrated Intel HD 3000 and discrete NVidia NVS 4200M GPU.
I posted my results here:
https://ikarios.wordpress.com/2015/10/2 ... nvs-4200m/
The results are quite interesting, CPU wise the X230 with its Intel Core i5-3320M CPU beats the W701 with Intel Core i7–720QM CPU by a big margin! In terms of GPU power the W701 destorys the other competitors
Best regards, Janni

I'm not really surprised.
The i7-720QM's Turbo clock is too low with 4 cores active--a paltry 166MHz increase from the 1.6GHz base clock; in contrast, the slowest Sandy Bridge quad-core i7 mobile (2630QM) has a base clock of 2.0GHz and a 4-core Turbo clock that's 600MHz higher, a more significant increase.
I suspect there's some cache contention going on as well-- some have mentioned that turning off HT improves the i7's performance a bit.

Some sandybridge/ivybridge dual core are known to benchmark higher than previous generation of quadcore.
Nice to see intel HD 3000 performing well in windows 10.

I'd chalk that to two things:hhhd1 wrote:Some sandybridge/ivybridge dual core are known to benchmark higher than previous generation of quadcore.
1. architectural improvements in Sandy and Ivy Bridge.
2. very aggressive Turbo Boost due to lower heat output.
