CPU Comparison

The Intel Core i7-2675QM and the Intel Processor N100 are both quad-core mobile parts, but they represent completely different eras of Intel engineering. The i7-2675QM is a 2011 Sandy Bridge chip with Hyper-Threading, while the N100 is a 2023 Gracemont-based processor designed for efficiency. The benchmark data shows a fascinating split: the older chip wins in one multi-core test, while the newer chip dominates single-core and another multi-core test.

Head-to-Head Benchmarks

The most striking result is in the Cinebench R23 multi-core test, where the Intel Core i7-2675QM scores 3118 against the N100's 2559.5. That is a 21.8% advantage for the 2011 processor, a significant margin that highlights the value of its 8 threads. The i7-2675QM's Hyper-Threading allows it to push ahead in this heavily threaded workload, despite its age.

However, the tables turn dramatically in the Cinebench R23 single-core test. Here, the Intel Processor N100 scores 910.5, which is 51.7% higher than the i7-2675QM's 440. This is a massive generational leap in per-core performance. The N100's Gracemont architecture is vastly more efficient at executing instructions, making it the clear winner for single-threaded tasks.

The Cinebench R15 multi-core test adds another layer to the story. The N100 wins this one with a score of 401.5, beating the i7-2675QM's 314 by 21.8%. This is interesting because it contradicts the R23 multi-core result. The likely explanation is that the R15 test is shorter and less demanding, allowing the N100 to sustain its boost clock of 3.40 GHz more effectively. The older i7-2675QM, with its higher 45W TDP, may not have the same short-burst performance capability.

Overall, the head-to-head data shows the N100 wins 2 out of 3 tests. The N100's victories are decisive in single-core and moderate in R15 multi-core, while the i7-2675QM's R23 multi-core win is equally decisive. The average benchmark scores are nearly identical: the i7-2675QM sits at 1012, and the N100 is at 1007, a difference of only 0.5%. This places them at the 28th and 27th percentiles of all CPUs, respectively. They are effectively peers in overall average performance, but with very different strengths.

Architecture Differences

The fundamental difference lies in the architecture. The Intel Core i7-2675QM is built on the Sandy Bridge architecture using a 32 nm process node, while the Intel Processor N100 uses the newer Gracemont architecture on a 10 nm node. This process shrink is a primary driver of the N100's efficiency and superior single-core performance.

The core counts are the same (4), but the thread counts differ. The i7-2675QM supports 8 threads via Hyper-Threading, whereas the N100 has only 4 threads. This explains the i7-2675QM's advantage in the Cinebench R23 multi-core test. The cache hierarchies also differ: the i7-2675QM has 64 KB of L1 and 256 KB of L2 per core, plus a 6 MB shared L3. The N100 has 96 KB of L1 per core and a 2 MB shared L2, but also has a 6 MB shared L3. The N100's larger L1 and shared L2 are designed for its efficient Gracemont cores.

The memory support is a major differentiator. The i7-2675QM uses dual-channel memory, whereas the N100 uses single-channel memory with a maximum bandwidth of 38.4 GB/s. This is a potential bottleneck for the N100 in memory-intensive tasks. The N100 also supports DDR4 and DDR5 memory, while the older chip has no listed memory support in the data.

The integrated graphics are different as well: the i7-2675QM features Intel HD 3000, while the N100 has UHD Graphics 730. The N100 also has a PCIe Gen 3 interface with 9 lanes, a detail not listed for the i7-2675QM. Finally, the production status and release dates are starkly different. The i7-2675QM is end-of-life and was released on 2011-10-11, while the N100 is active and was released on 2023-01-02. The N100 has a launch MSRP of $128.

FAQ

Q: Which processor has more threads?

A: The Intel Core i7-2675QM has 8 threads thanks to Hyper-Threading, while the Intel Processor N100 has 4 threads.

Q: Why does the older i7-2675QM win in Cinebench R23 multi-core?

A: The i7-2675QM's 8 threads allow it to process more parallel work, giving it a 21.8% score advantage over the N100 in that specific test.

Q: Is the N100 always faster in multi-core tests?

A: No. The N100 wins Cinebench R15 multi-core by 21.8%, but loses Cinebench R23 multi-core by the same 21.8% margin to the i7-2675QM.

The Verdict

The data paints a clear picture for different use cases. The Intel Processor N100 is the better choice for most modern, everyday workloads. Its 51.7% lead in single-core performance makes it far more responsive for web browsing, office applications, and general system navigation. Its much lower 6W TDP also makes it ideal for fanless or low-power designs.

The Intel Core i7-2675QM is only preferable in a narrow scenario: heavily multi-threaded applications that can fully utilize its 8 threads. In the Cinebench R23 multi-core test, it is 21.8% faster than the N100. If you are running a specific workload that scales perfectly across 8 threads, the older chip has an edge. However, its 45W TDP and end-of-life status make it a poor choice for new builds.

For a modern system, the N100 is the logical pick. Its superior single-core performance and efficiency make it a more future-proof and practical processor. The i7-2675QM is a relic that only makes sense if you have a specific multi-threaded application that needs its thread count and you can manage its power draw. The overall average scores are nearly tied, but the N100's wins are in more impactful areas.
