Benchmarks
System setup
Below is a complete set of Intel Core 2 Duo T5550 and i3-350M (PGA988) benchmarks from our CPU benchmark database. The former processor was tested on MSI Fuzzy GM965 (MS-9803 V1.0) motherboard with 2GB dual-channel Corsair CM2X1024-6400C4 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400). The latter processor was tested on Jetway NF98-QM57-LF motherboard, that had 2 GB dual-channel Crucial CT2KIT12864BC1339 DDR3-1333 SODIMM memory, and Integrated on-chip Intel Westmere graphics.
All tests were performed at default frequency and voltage, using manufacturer's stock fan/heatsink. None of the components were overclocked. Motherboard BIOS options were left at default settings.
The results of all benchmarks are broken into four categories: multi-threaded, single-threaded, memory intensive and graphics / gaming.
Core 2 Duo T5550 vs i3-350M (PGA988) single-threaded benchmarks
Single-threaded benchmarks run on a single CPU core, and do not depend on such features as the number of cores, or Hyper-Threading technology. Additionally, they do not utilize on-chip caches, dedicated to other cores.

Core 2 Duo T5550 vs i3-350M (PGA988) graphics benchmarks
Graphics benchmarks depend on the type of integrated or discrete graphics adapter, and to less extent on the processor performance. Because these benchmarks are synthetic, they may not truly represent gaming performance. However, they still can used to estimate whether one processor will perform faster or slower in games than another CPU.

Core 2 Duo T5550 vs i3-350M (PGA988) memory performance
Memory-intensive tests or programs move large amounts of data to/from memory, and they depend more on memory throughput and the size of on-chip caches, rather than on CPU integer/FP/SIMD performance.
