Core i5-2515E vs Core i7-2637M

Both the Core i5-2515E and Core i7-2637M share an identical 2-core/4-thread configuration. Boost clocks reach 2.5 GHz on the Core i5-2515E versus 2.8 GHz on the Core i7-2637M — a 11.3% clock advantage for the Core i7-2637M (base: 2.5 GHz vs 1.7 GHz). Both are built on the Sandy Bridge (2011−2013) architecture using a 32 nm process. In PassMark, the Core i5-2515E scores 1,882 against the Core i7-2637M's 1,889 — a 0.4% lead for the Core i7-2637M. Geekbench 6 single-core — the metric most relevant to gaming — records 530 vs 350, a 40.9% lead for the Core i5-2515E that directly translates to higher frame rates. L3 cache: 3 MB (total) on the Core i5-2515E vs 4 MB on the Core i7-2637M.

Both processors use the BGA1023 socket with PCIe 2.0. Maximum memory speed reaches DDR3-1333 on the Core i5-2515E versus 1333 on the Core i7-2637M — the Core i7-2637M supports 199.1% faster memory, which can translate to measurable gains in memory-sensitive workloads. The Core i5-2515E supports up to 16 GB of RAM compared to 8 — 66.7% more capacity for professional workloads. Both feature 2-channel memory with ECC support. Both provide 16 PCIe lanes. Chipset compatibility: HM65,QM67 (Core i5-2515E) and HM65,HM67,QM67 (Core i7-2637M).

Neither processor supports overclocking. Virtualization support: VT-x, VT-d, EPT (Core i5-2515E) vs true (Core i7-2637M). Both include integrated graphics — HD Graphics 3000 (Core i5-2515E) and Intel HD Graphics 3000 (Core i7-2637M) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i5-2515E targets Embedded. Direct competitor: Core i5-2515E rivals Embedded R-Series.

The Core i5-2515E launched at $0 MSRP, while the Core i7-2637M debuted at $289.
