CPU World reports Intel's first Haswell-based Celeron desktop processors have hit the market. The boxed versions of the G1820 and G1830 can be found at e-tailers for around $48 and $56, respectively.
Celeron G1820T, G1820 and G1830 have exactly the same specs as Ivy Bridge-based G1620T, G1620 and G1630. All microprocessors have 2 CPU cores, that share a 2MB third level cache. The processors also integrate HD graphics, clocked at 1050 MHz, and come with on-chip memory controller, that supports memory up to DDR3-1333. The Celerons incorporate only basic instruction set extensions, such as Intel 64 and SIMD instructions up to SSE4. They also support virtualization technology. The G1820T runs at 2.4 GHz, and fits into 35 Watt thermal envelope. The G1820 and G1830 have 2.7 GHz and 2.8 GHz clock speeds, and 54 Watt TDP. The new Celerons require socket 1150 motherboards. Since the G1800 series processors are based on more efficient architecture, they perform 1% - 10% better than their Ivy Bridge predecessors, or 6% better on average.
