GTX 680: PhysX Benchmarks roundup
Finally, NVIDIA has officially presented their new GPU – GTX 680, built on 28nm GK104 chip, which itself is based on next-gen Kepler architecture.
Many rumors were floating around Kepler and its physics acceleration capabilities, some were endowing new GPU with dedicated PhysX blocks, others were claiming ability to run CPU PhysX games in hardware – none of this happens to be true. Nothing special (like NVENC video encoder) for physics calculations, just general improvements to chip architecture, SM clusters, etc.
Nonetheless, we will try to gather all available information regarding PhysX computation performance of the GTX 680, in comparison to previous generation GPUs.
NVIDIA Kepler GPU GeForce GTX 680 Video Card Review by HARDOCP
Interesting results – in this case, GeForce GTX 680 performance is higher than Radeon HD 7970 even with GPU PhysX effects enabled. However, we can not directly compare GTX 580 and GTX 680 due to different resolution settings.
Alice: Madness Returns will feature GPU PhysX effects
In a recent promo video for upcoming GTX 560 GPU, NVIDIA has spoiled next game with support of GPU accelerated PhysX effects – Alice: Madness Returns, sequel to American McGee’s visionary classic “Alice” title.
UPDATE: Comparison GPU PhysX video
Starting at 1:34, comparison PhysX sequences are showcased. According to the video, GPU PhysX content in Alice will include (following list may be not full) destructible environments..

GT 240 as dedicated PhysX card: benchmarks
PCPOP.com website has published a bunch of benchmarks where GT 240, low-end 40nm GPU from Nvidia, is used as dedicated PhysX card alongside with GTX 260. System used for tests.
Performance with PhysX content, running on dedicated GT 220 (marked yellow on graph) is compared to a single GTX 260, calculating graphics and PhysX effects simultaneously (marked green).

EVGA GTX 275 CO-OP PhysX: Under the Hood
EXPreview.com website has published detailed pics of EVGA GTX 275 CO-OP PhysX – card with exceptional design, which combines two different GPU, G200 (GTX 275) and G92 (GTS 250), on one PCB.
55nm GT200b graphics-rendering chip (left one on a pic below) operates at a 633MHz core, 1296MHz shaders and has 896MB of GDDR3 memory, running at 2268MHz. 55nm G92b chip (right one), fully dedicated to PhysX processing, runs at a 738MHz core, 1836MHz shaders, and has 384MB of 2200MHz GDDR3 memory.
Cooling system consist of two heatsinks with heatpipes, fan in the middle.
