According to CPU World the chips should hit the shops in the second quarter of 2013 which is a quarter after January's refresh of budget desktop families, and one quarter before the launch of Haswell. The new chips have the original titles of Pentium G2030, G2030T, G2120T and G2140. They will have two cores, but lack Hyper-Threading technology, and can run two threads before getting all confused.
Both the G2000 and G2100 series CPUs support only basic features, like Intel 64 and Virtualization. They do integrate HD graphics which are clocked at 650 MHz and dual-channel memory controller, that supports DDR3-1333 on the G2030 and the G2030T, and up to DDR3-1600 on the G2120T and the G2140.
Pentium G2030T and G2120T are low-power models, replacing G2020T and G2100T but are clocked 100 MHz higher, that is at 2.6GHz and 2.7GHz respectively. However they still fit into 35 Watt thermal envelope. Pentium G2030 and G2140 mainstream microprocessors will be faster than "T" SKUs, and they will have 57 per cent higher TDP. Intel expects these to replace the G2020 and G2130 SKUs. The G2030 will run at 3 GHz. The G2140 will operate at 3.3 GHz. No word on prices yet.
