Subjective framerates looked similar to a GT650M according to Anandtech:

The settings were 1920X1080 at high with shadows at medium.
This is GT3 version which uses embedded RAM although the graphics were tested in a desktop,against a laptop with the GT650M,so I assume it is one of the desktop chips. The other versions,ie,GT1 and GT2 use system RAM. It is unclear whether the GT3 also has a version without eDRAM and whether the GT650M used was the GDDR3 or GDDR5 version as the GDDR5 is used in the Apple laptops.
Bit-tech is the only review site which I can see which has tested the HD4000 with DiRT3 at 1920X1080 using DX11:

However,the low setting was used and not the high settings like with the Anandtech test. OTH,Anandtech does not state whether DX9 or DX11 was used.
The desktop A10-5800K can hit nearly 40FPS at 1920X1080 with all settings set to high(including shadows) and no AA:

The A10-5800K tends to get a 3DMark11 score of around 1500 points and the A10-4600M around 1150,ie,around 30% higher.
I don't know what the impact of going from high to medium shadows is,but it does look like,the GT3e should at least match the IGP in the A10 4600M if DX11 was used in the demo or maybe exceed it.
