Ivy Bridge Dual-Core from Intel
Taiwan PC enthusiast Coolaler Ivy Bridge has a new dual-core LGA1155 engineering sample to play with, and he wasted no time in putting through some tests. The sample has two cores, four threads with HyperThreading enabled, clock speed of 1.80 GHz, 256 KB of L2 cache per core and 4 MB of shared L3 cache. And ‘running on an Intel P67 chipset based motherboard with 8 GB of dual-channel DDR3-1600 MHz to 1.80 GHz, could not be left for absolute performance figures since it is unlikely that Intel will release a chip with the clock speed unless it is unreal performance: clock gains over Sandy Bridge, but it’s good enough for the clock-to-clock comparison of performance between Ivy Bridge and Sandy Bridge. A i5-2400 has been clocked at 1.80 GHz with 18x multiplier BClk, and subjected to a single thread of reference, and a multithreaded one.
The cache and memory benchmark that measures bandwidth and latency of caches and memory was unable to measure bandwidth, but measured some latencies. The L1 cache at 2.2 nanoseconds (ns), and L2 at 2.9 ns. Next, the Ivy Bridge DC, and the Core i5-2400 (@ 1.80 GHz) testbeds were put through CPUMark 99, where that’s DC scored 278 points, and Core i5-2400 clocked at 1.80 GHz scored closely followed at 276 points. Moving on to multithreaded performance, the two were put through Cinebench 11.5 64-bit. Thats DC chip scored 1.81 points; while the Core i5-2400 clocked at 1.80 GHz, scored 2.61 points. Coolaler promises more benches.
