About Intel Core i7-920XM
The Intel Core i7-920XM is a 4-core, 8-thread mobile processor from the Clarksfield generation, released on 2009-09-22 with a launch MSRP of $1096. It was an Extreme edition part, but its average benchmark score of 623 places it at the 14th percentile of all CPUs in the database. Against its nearest rivals, the i7-920XM is effectively tied with several Celeron parts and a mid-range mobile Core i5, trailing by 0.2–0.3% in average score. The data shows a once-flagship mobile chip that now performs on par with entry-level processors.
Benchmark Performance
The i7-920XM produces a Cinebench R23 multi-core score of 1701 and a single-core score of 240. In Cinebench R20, the multi-core result is 714 and single-core is 100. Cinebench R15 multi-core yields 171. Geekbench results are 1064 multi-core and 373 single-core. These absolute numbers are low, which is consistent with the 14th percentile ranking. The average benchmark score across all tests is 623.
The nearest rivals are all within a fraction of a percent. The Intel Celeron 4305U, Celeron N4505, and Celeron G3900 each have an average score of 624, putting the i7-920XM 0.2% behind each. The Intel Core i5-2450M averages 625, a 0.3% gap. This means the i7-920XM’s performance is statistically indistinguishable from these later, lower-tier parts. The multi-core advantage of having four physical cores and eight threads does not translate into a meaningful lead over dual-core Celerons or the i5-2450M, which also has two cores and four threads. The 14th percentile confirms that the vast majority of CPUs in the database outperform it.
Power and Thermals
The i7-920XM has a TDP of 55W, which is the thermal design power for this mobile processor. It is built on a 45nm process node with 774 million transistors on a 296 mm² die. The 55W TDP class implies that a laptop chassis must dissipate that heat, and the 45nm process means the thermal density is significant. The multiplier is unlocked, so users can push the boost clock beyond the stock 3.20 GHz, which would increase power draw and heat output. There is no integrated graphics, so the CPU alone contributes to the thermal load, but a discrete GPU is required for any display output. For a mobile part, a capable cooling solution is necessary, especially when overclocking is considered.
How It Compares
Intel Celeron 4305U: The i7-920XM trails this Celeron by 0.2% in average benchmark score. The Celeron is a low-power dual-core, while the i7-920XM has four cores and eight threads, yet the performance is essentially equal. The i7-920XM’s higher core count does not yield a practical advantage in the measured workloads.
Intel Celeron N4505: Again, the i7-920XM is 0.2% behind the N4505’s average score of 624. The N4505 is a dual-core design, and the i7-920XM’s extra threads do not close the gap. The benchmark data shows that the older Extreme part cannot outperform this entry-level Celeron.
Intel Celeron G3900: The delta is the same – 0.2% behind the G3900’s 624 average. The G3900 is a desktop dual-core without hyper-threading, yet it matches the i7-920XM’s multi-core results. This underscores how far the i7-920XM has fallen relative to even basic modern processors.
Intel Core i5-2450M: The i5-2450M averages 625, putting the i7-920XM 0.3% behind. The i5-2450M is a dual-core with hyper-threading, and despite having half the physical cores, it edges out the i7-920XM. The i7-920XM’s higher boost clock of 3.20 GHz and larger L3 cache (8 MB shared) do not compensate for the architectural improvements in the later part.

Who Should Consider It
Given its 14th percentile standing and scores that match entry-level Celerons, the i7-920XM is not suitable for modern gaming, content creation, or heavy multi-threaded workloads. The Cinebench R23 multi-core score of 1701 and Geekbench multi-core of 1064 are far too low for contemporary applications. It could handle basic office tasks or legacy software, but its 55W TDP and lack of integrated graphics make it an inefficient choice for such use. The only realistic scenario is a collector or enthusiast building a period-correct laptop, or someone with a Socket G1 system who wants the highest-end part available for that platform. Even then, the performance is not competitive with even the cheapest modern processors.
Single-Thread vs Multi-Thread Behavior
The i7-920XM has a base clock of 2.00 GHz and a boost clock of 3.20 GHz. In Cinebench R23, it scores 240 single-core and 1701 multi-core. The multi-core score is substantially higher than the single-core score, indicating that the eight threads are effectively utilized. The Geekbench results show a similar pattern: 373 single-core and 1064 multi-core. However, the absolute single-core performance is very low, meaning any task that relies on one core will feel sluggish. The multi-core scaling is good for a quad-core design, but the per-core performance is so weak that even the multi-core results remain below the level of modern dual-core parts. This split suggests the processor is better suited to parallelizable workloads than to lightly-threaded tasks, but the overall low scores limit its usefulness in either category.
Platform and Compatibility
The i7-920XM is based on the Nehalem architecture (codename Clarksfield) and is manufactured on a 45nm process. It uses Intel Socket G1 and supports DDR3 memory in a dual-channel layout, with a bandwidth of 21.3 GB/s. ECC memory is not supported. The CPU provides PCIe Gen 2 with 16 lanes from the processor itself. There is no integrated graphics, so a discrete GPU is mandatory. The platform is end-of-life, and the only upgrade path would be to another Socket G1 processor, though none are listed in the data. The part number is SLBLWQ2YFQ3B8, and the multiplier is unlocked, offering overclocking potential within the thermal limits of the 55W TDP. The memory bus and PCIe capabilities are fixed by the platform, and the lack of ECC and integrated graphics further narrows its applicability.
