The performance of the Intel HD Graphics 3000 can indeed be called impressive. In many older and current gaming titles it competes at a level of entry-level graphics cards like the Geforce G 310M, the GT 220M or the ATI HD5470. It multiplies the performance of the previous Intel GMA HD solution. In practice this means that older games can be played at high graphics settings and current games mostly at low graphics details.
Concerning the integrated Intel HD Graphics 3000, you should keep in mind that it is - depending on the CPU - differently clocked. While the tested i7-2720QM CPU clocks the graphics chip at 650 up to 1300 MHz, the clock rate of the GPU only ranges from 650-1200 MHz in the i7-2635QM or from 650-1100 MHz in the i7-2630QM. In ULV processors the clock rate is even lower at 350-900 MHz. So, the performance drops accordingly. The same is true for systems with slender cooling capacities, because this might hinder the turbo function in achieving the maximum performance boost.
Contrary to the GMA HD, Intel HD Graphics 3000 is directly integrated in the processor core of the Sandy-Bridge processors. Alike its predecessor it does not have a dedicated graphics memory, but, can access the Level-3 cache of the CPU (which is now called 'Last Level Cache' - LLC) of up to 8 MB, depending on the CPU. Further memory requirements are covered by accessing the RAM of the computer.
Alike the actual cores of the CPU, the integrated HD Graphics 3000 can dynamically adjust its clock rate upon increased load (Turbo Boost). However, some processors of the Sandy-Bridge family handle this feature differently. E.g., the clock rates range from 650 MHz to a maximum of 1300 MHz in the new i5/i7-2X20 or i5/i7-2X40 M/QM/XM processors, while the i3-2310M and also the i7-2630QM use a clock rate between 650 and 1100 MHz and the i5-2410M and the i7-2635QM between 650-1200 and are therewith lower clocked. ULV processors, e.g., the i7-2617M have an even lower clock rate of 350 to 900MHz, so, the performance should drop accordingly. The Intel HD Graphics 3000 has 12 Execution Units (comparable to pipelines). Despite the same number than in the GMA HD, they have been improved and are now clearly faster than in the predecessor.
