AMD Phenom II X4 910

The AMD Phenom II X4 910 is a 4-core, 4-thread desktop processor from the Deneb generation, released in 2009. Built on the 45 nm K10 architecture, it runs a 2.60 GHz base clock with no boost clock documented, and combines 128 KB of L1 cache per core, 512 KB of L2 cache per core, and 6 MB of shared L3 cache. Its average benchmark score of 519 places it at the 9th percentile of all CPUs in the database, and its nearest rivals are all within a 0.5% delta band of that score.

Who Should Consider It

The Cinebench results point to a CPU aimed at lighter workloads rather than demanding modern rendering. The multi-core scores — 151 in Cinebench R15, 633 in R20, and 1509 in R23 — are all low in absolute terms, so users with heavily threaded creation tasks such as video rendering or 3D scene production will likely find the Phenom II X4 910 underpowered. The single-core scores are also modest: 89 in R20 and 213 in R23. That makes the chip a weak match for software that relies on a small number of fast cores.

For desktop productivity, however, the 4 physical cores still provide a workable baseline for basic multitasking and lightly threaded office-style applications. The 6 MB shared L3 cache could help workloads that share data between cores, but the overall 9th-percentile standing indicates limited headroom. Gamers should note that no gaming-specific benchmark appears in the data; the only documented tests are Cinebench variants. Because the integrated graphics are listed only as a chipset feature on certain motherboards, the processor itself does not appear to provide a display output directly. Builders planning to use this CPU for any visual workload would need a platform that offers a graphics solution through the motherboard chipset or a separate graphics card.

Power and Thermals

The TDP is 95W, which places the Phenom II X4 910 in the 95W-class desktop cooling tier. The physical details behind that thermal requirement include a 45 nm process node, a die size of 258 mm², and 758 million transistors. With no boost clock listed, the only documented operating clock is the fixed 2.60 GHz base clock, meaning all-core workloads will run at that frequency. The production status is end-of-life, so no future thermal or power guidance should be expected. In practice, a cooling solution designed for a 95W processor should correspond to this chip’s thermal class.

Benchmark Performance

The benchmark profile is consistently low overall. In Cinebench R15 multi-core, the score is 151; in R20 multi-core, it is 633; and in R23 multi-core, it is 1509. Single-core performance is even more constrained, with R20 single-core at 89 and R23 single-core at 213. The average benchmark score is 519, which aligns with the 9th-percentile position among all CPUs in the database.

The nearest rivals confirm that this processor sits in an extremely tight performance cluster. The Intel Celeron G1840 has an average score of 520 with a delta of -0.3%. The Intel Xeon L5408 has an average score of 517 and a delta of +0.3%. The Intel Core i3-3110M also averages 517, with a delta of +0.4%. Finally, the AMD PRO A6-9500 averages 521, with a delta of -0.5%. In other words, every nearest rival falls within a half-percent of the Phenom II X4 910, so the differences are essentially rounding-level in the pooled benchmark data.

How It Compares

Intel Celeron G1840: The Phenom II X4 910 averages 519 against the Celeron’s 520, a 0.3% delta in the Celeron’s favor. These two effectively land at the same performance level, despite being from different platforms and generations.

Intel Xeon L5408: The Phenom II X4 910 is 0.3% ahead of the Xeon L5408, with averages of 519 and 517. The benchmark result places them in the same performance class, separated only by rounding-level noise.

Intel Core i3-3110M: The Phenom II X4 910 is 0.4% ahead of the Core i3-3110M, again by 519 to 517. The i3’s mobile orientation does not appear to create a meaningful gap in the pooled benchmark average.

AMD PRO A6-9500: The Phenom II X4 910 is 0.5% behind the AMD PRO A6-9500, with averages of 519 and 521. This is the largest nearest-rival delta in the group, yet it remains a narrow gap.

FAQ

Q: What kind of memory does the Phenom II X4 910 support?

A: It supports DDR3 memory over a dual-channel memory bus, with a documented memory bandwidth of 21.3 GB/s. ECC memory support is enabled.

Q: Is the multiplier unlocked for overclocking?

A: No. The multiplierUnlocked field is false, so the clock multiplier is not unlocked.

Q: Does the processor include integrated graphics?

A: The integrated graphics are described as “on certain motherboards” and as a chipset feature, not as a feature of the processor itself.

Q: What socket does the Phenom II X4 910 use?

A: It uses AMD Socket AM3.

Q: What is the production status?

A: The production status is end-of-life.

Q: What is the base clock and is there a boost clock?

A: The base clock is 2.60 GHz. The boost clock field is null, so no boost clock is documented.

Platform and Compatibility

The Phenom II X4 910 is built for AMD Socket AM3, making the compatible platform one that accepts that socket. Memory support is DDR3 with a dual-channel bus and 21.3 GB/s of bandwidth, and the ECC memory flag is true. The PCIe interface is Gen 2. Because integrated graphics are listed only as a chipset feature on certain motherboards, display connectivity depends on the board’s chipset implementation rather than the CPU. The multiplier is locked, so CPU ratio adjustment is not available. The architecture is K10 with the Deneb codename, and the process node is 45 nm. With a production status of end-of-life, no ongoing platform expansion is indicated in the data.

Single-Thread vs Multi-Thread Behavior

The split between single-core and multi-core scores is instructive. In Cinebench R20, the single-core score is 89 while the multi-core score is 633. In R23, the single-core score is 213 while the multi-core score is 1509. Those results show that the multi-core score is significantly higher than the single-core score, which is the expected pattern for a part with 4 physical cores and 4 threads. There is no indication of simultaneous multithreading; the thread count equals the core count, so multi-threaded scaling comes entirely from the physical cores.

The single-thread scores are low in absolute terms. That means workloads with long serial portions will be limited by the 2.60 GHz base clock and the older architecture. Conversely, tasks that split cleanly across all 4 cores have a larger performance pool to draw from. The shared 6 MB L3 cache sits behind the per-core L2 caches, so multi-threaded workloads that share data across cores may benefit from the common cache. Overall, the data describes a classic balanced quad-core of its era, but the 9th-percentile standing leaves little room for demanding modern single-threaded or highly multi-threaded workloads.
