AMD Athlon II X2 245

The AMD Athlon II X2 245 is a desktop processor released on 2009-07-22 and now listed as end-of-life. It uses the K10 architecture, carries the Regor codename, and is built on a 45 nm process with 410 million transistors on a 117 mm² die. The chip has 2 cores and 2 threads, a 2.90 GHz base clock, and no boost clock in the data. It fits AMD Socket AM3, supports dual-channel DDR3 memory, and includes PCIe Gen 2 connectivity. Cache totals are 256 KB of L1 and 2 MB of L2, with no L3 cache. The part number is ADX245OCK23GQ. In the benchmark database, the Athlon II X2 245 has an average benchmark score of 330 and sits in the 1st percentile of all CPUs.

How It Compares

Against the Intel Celeron G530, the Athlon II X2 245 is effectively tied. The Celeron's average benchmark score is 330, matching the 245's average of 330, and the nearestRivals delta is -0.1 percent. The delta sign indicates the Celeron is very slightly ahead in aggregate, but the equal rounded scores show that the difference is not material.

Against the AMD Athlon II X2 245e, the 245 records a 0.3 percent delta. The 245e averages 329, while the 245 averages 330. That 0.3 percent spread is small enough that the two parts occupy the same performance neighborhood.

Against the Intel Xeon W3503, the 245 is ahead by 0.5 percent in deltaPct. The Xeon averages 328, while the 245 averages 330. The lead exists, but it is narrow.

Against the AMD Phenom II X2 B53, the 245 trails by 0.7 percent in deltaPct. The Phenom averages 332, the highest average among the named rivals. The 245's 330 average is below that mark, but the 0.7 percent gap remains modest.

Who Should Consider It

The benchmark data does not paint a picture of high absolute performance. The 1st percentile ranking means the Athlon II X2 245 sits below nearly the entire field of CPUs in the database. For gaming, the low single-core scores and the 2-core/2-thread structure leave little headroom; the R20 single-core result is 56, and the R23 single-core result is 135. These are not scores that suggest smooth performance in demanding game workloads.

For content creation, the multi-core Cinebench results are equally modest. The R15 multi-core score is 96, the R20 multi-core score is 403, and the R23 multi-core score is 960. Anything that relies on sustained rendering across multiple threads will be constrained by the 2-thread ceiling and a design that lists no boost clock.

For office-style productivity, the situation is less clearly negative. The processor handles 2 threads in parallel, and the R20 multi-core score of 403 shows that dual-threaded workloads get more work done than the single-core score of 56 would suggest. Simple office-style tasks with low thread demand sit within the performance envelope, but the data does not indicate spare capacity for heavy multitasking.

Overall, the end-of-life status and Socket AM3 requirement mean this processor is best considered for platforms already built around that socket. The data supports light-duty use rather than demanding gaming or creation workloads.

Benchmark Performance

The benchmark performance of the Athlon II X2 245 is defined by low absolute Cinebench numbers. In Cinebench R15 multi-core, the score is 96. In Cinebench R20, the multi-core score is 403 and the single-core score is 56. In Cinebench R23, the multi-core score is 960 and the single-core score is 135. All of these results are low in absolute terms, and the overall percentile is 1.

Comparing the 245 to its nearest rivals using aggregate average score, the spread is narrow. The Intel Celeron G530 has an average benchmark score of 330, equal to the 245's 330, with a delta of -0.1 percent. The AMD Athlon II X2 245e has an average of 329 and a delta of 0.3 percent. The Intel Xeon W3503 has an average of 328 and a delta of 0.5 percent. The AMD Phenom II X2 B53 has an average of 332 and a delta of -0.7 percent. These deltas are tiny, so in aggregate terms the nearest rivals are not meaningfully separated from the 245.

The proximity of the nearest rivals means the 245's relative position is not characterized by clear wins or losses. Instead, the aggregate scores cluster around 330, with the 245 at the center of that cluster. The individual Cinebench results confirm that the 245 is a dual-threaded processor with limited throughput in both single-core and multi-core tests.

FAQ

Q: What socket does the AMD Athlon II X2 245 use?

A: AMD Socket AM3.

Q: Does the Athlon II X2 245 support ECC memory?

A: No. The fact pack sets ECC memory support to false.

Q: What memory does it support?

A: DDR3 memory, with a dual-channel memory bus.

Q: Is the multiplier unlocked?

A: No. The multiplierUnlocked field is false.

Q: Does it include integrated graphics?

A: Integrated graphics are listed as a chipset feature on certain motherboards, not as a processor component in the data.

Q: What is the production status?

A: End-of-life.

Power and Thermals

The Athlon II X2 245 is rated at a 65 W TDP. This places it in a modest power class. The CPU uses a 45 nm process, has 2 cores, and runs at a 2.90 GHz base clock with no boost clock; the data does not list a higher operating state to elevate thermal load. From a cooling standpoint, a standard air cooler is the appropriate tier. The thermal envelope is small enough that high-end liquid cooling or oversized tower coolers are unnecessary based on the TDP class.

Single-Thread vs Multi-Thread Behavior

The benchmark set includes both single-thread and multi-thread Cinebench results. The R20 single-core score is 56, and the R20 multi-core score is 403. The R23 single-core score is 135, and the R23 multi-core score is 960. In both Cinebench revisions, the multi-core result is much larger than the single-core result. This suggests that applications designed to use multiple threads can gain a meaningful increase over the single-thread baseline.

At the same time, the 245 has 2 cores and 2 threads, so it cannot process more than 2 threads simultaneously. The single-thread results are low in absolute terms. Therefore, the multi-core advantage only goes so far. Single-thread-bound applications will rely on the 2.90 GHz base clock and cannot benefit from any boost state. Multi-thread-bound applications will see the benefit of both cores, but the 2-thread ceiling limits scaling.

Real-world behavior follows from that split. Lightly threaded tasks will see low but consistent single-thread performance. Multi-threaded tasks such as Cinebench renders will use both cores and produce results like the R20 multi-core score of 403 and the R23 multi-core score of 960. The difference between the R20 single-core score of 56 and the R20 multi-core score of 403 is the strongest evidence in the data that the 2 available threads can be put to work effectively once a workload is written to use them.
