AMD Athlon 240GE vs Intel Xeon E5-2609 v3 Comparison

The AMD Athlon 240GE and Intel Xeon E5-2609 v3 occupy very different corners of the processor market, yet their benchmark scores place them in an unexpectedly tight contest. The Athlon is a modern, low-power desktop chip from AMD’s Zen family, while the Xeon is an older, server-oriented part from Intel’s Haswell generation. The recorded data shows a curious situation: in every single Cinebench test, the Athlon 240GE edges out the Xeon, but the margins are so narrow that the two chips effectively trade blows in real-world terms. This raises the question: does the newer architecture truly dominate, or does the Xeon’s extra cores compensate for its age? The numbers below provide a detailed look.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent. Across all six recorded Cinebench tests, the AMD Athlon 240GE wins every round, but the largest margin is just 1.1%. In Cinebench R15 multicore, the Athlon scores 390 against the Xeon’s 386, a delta of 1%. The single-core run in R15 is a dead tie at 54 for both chips, though the database still credits the Athlon with a win due to a 0% delta. Moving to Cinebench R20, the Athlon posts 1627 in multicore versus 1611 for the Xeon, again a 1% lead. The R20 single-core result shows 229 for the AMD part and 227 for the Intel part, a 0.9% margin. In Cinebench R23, the multicore scores are 3876 for the Athlon and 3836 for the Xeon, a 1% difference, while single-core comes in at 547 and 541, respectively, a 1.1% edge for the AMD chip.

What stands out here is not the direction of the results, but their tightness. A 1% or 1.1% lead is within the noise of many benchmarking runs, and the fact that the Athlon wins all six tests suggests a slight architectural advantage rather than a decisive one. The Xeon, despite having three times the cores (6 versus 2), cannot overcome the Athlon’s per-core efficiency in these workloads. In R15 single-core, the exact tie at 54 points indicates that both chips deliver identical throughput on a single thread, which is surprising given the Xeon’s much lower base clock of 1900 MHz compared to the Athlon’s 3500 MHz. The Xeon’s Haswell architecture evidently compensates for its clock deficit in single-threaded work, but the Athlon’s Zen core still manages to pull ahead, however slightly.

The average benchmark scores reflect this closeness. The Athlon’s average is 1121, while the Xeon’s is 1109, a difference of just 12 points or roughly 1%. In percentile terms, the Athlon sits at the 32nd percentile of all CPUs, while the Xeon sits at the 31st. These are nearly identical positions, meaning both chips land in the same performance tier according to the database’s broader ranking. The nearest rivals for the Athlon include the Intel Xeon D-1518 with an identical average score of 1121, the Intel Core i7-2860QM at 1120 (0.1% behind), and the Intel Core i3-4150 at 1119 (0.2% behind). For the Xeon, the nearest rivals are the Intel Core i5-4570T at 1108 (0.1% behind), the Intel Xeon E5630 at 1110 (0.1% ahead), and the Intel Core i7-5557U at 1110 (0.1% ahead). This clustering around the 1100 to 1120 range underscores that both processors occupy a similar performance envelope, regardless of their architectural differences.

Where Each One Wins

From a pure benchmark standpoint, the Athlon 240GE wins every recorded test, so the use-case split is not about which chip scores higher, but rather about what the scores imply for different workloads. The Athlon’s wins are all in Cinebench, a rendering workload that scales with both core count and clock speed. With only 2 cores and 4 threads, the Athlon still beats a 6-core Xeon in multicore tests. This suggests that for lightly threaded applications, such as everyday desktop tasks, web browsing, or office productivity, the Athlon’s higher base clock and newer Zen architecture provide a tangible benefit. The single-core ties and narrow wins indicate that the Athlon is at least as good as the Xeon in any task that relies on one or two threads, and often slightly better.

The Xeon’s case for preference rests on factors not captured in the benchmark scores. It supports ECC memory, which the Athlon does not, making it suited for error-sensitive server or workstation environments. Its quad-channel memory bus provides a theoretical bandwidth of 51.2 GB/s, compared to the Athlon’s dual-channel 42.7 GB/s, which could benefit memory-intensive workloads like large database queries or virtualized environments. The Xeon also offers 40 PCIe Gen 3 lanes, versus the Athlon’s 8 lanes, allowing for far more expansion cards, storage controllers, or GPUs. However, the recorded benchmarks do not test these aspects, so the data alone cannot confirm a performance advantage in such scenarios. What the data does show is that in CPU-bound rendering tasks, the Xeon does not win a single test, so any hypothetical advantage would have to come from memory bandwidth, ECC stability, or I/O capacity, not raw compute throughput.

FAQ

Q: Why does the Athlon 240GE win every benchmark despite having fewer cores?

A: The Athlon has 2 cores and 4 threads, while the Xeon has 6 cores and 6 threads. However, the Athlon’s base clock is 3.50 GHz compared to the Xeon’s 1.90 GHz. The recorded Cinebench scores show the Athlon ahead by 1% or less in all tests, indicating that its higher clock speed and Zen architecture compensate for the core deficit in these workloads.

Q: Is the Athlon 240GE significantly faster than the Xeon E5-2609 v3 in single-core tasks?

A: No. In Cinebench R15 single-core, both chips score exactly 54. In R20, the Athlon scores 229 versus 227 for the Xeon, a 0.9% difference. In R23, the Athlon scores 547 versus 541, a 1.1% difference. The margins are minimal, so the Athlon is only marginally better in single-threaded performance.

Q: What is the average benchmark score difference between the two?

A: The Athlon has an average benchmark score of 1121, while the Xeon has 1109. This is a difference of 12 points, or roughly 1%. The Athlon sits at the 32nd percentile of all CPUs, and the Xeon sits at the 31st.

Q: Does the Xeon E5-2609 v3 support ECC memory?

A: Yes, the Xeon supports ECC memory, while the Athlon does not. This is a key differentiator for server or workstation use where memory error correction is critical. The Athlon’s memory support is DDR4 with dual-channel access, while the Xeon also uses DDR4 but with quad-channel access.

Q: How do the two chips compare in terms of memory bandwidth?

A: The Xeon offers a memory bandwidth of 51.2 GB/s due to its quad-channel bus, while the Athlon provides 42.7 GB/s over a dual-channel bus. The Xeon’s bandwidth is higher, which could benefit memory-heavy workloads, but the recorded Cinebench tests do not show a corresponding performance advantage.

Q: Which chip has a higher TDP?

A: The Xeon has a TDP of 85 watts, while the Athlon has a TDP of 35 watts. This means the Athlon consumes far less power, which could be relevant for thermal management or energy efficiency, though the database does not include power consumption benchmarks.

The Verdict

The data points to a clear winner in raw compute performance: the AMD Athlon 240GE. It wins all six Cinebench tests, holds a higher average benchmark score (1121 versus 1109), and achieves a higher percentile ranking (32 versus 31). For anyone choosing between these two solely on the basis of CPU rendering or single-threaded speed, the Athlon is the better pick. Its 1% to 1.1% margins are small, but they are consistent across every test, and its lower TDP of 35 watts makes it a more efficient choice for desktop use.

However, the Xeon E5-2609 v3 is not without merit for specific buyers. The data shows it matches the Athlon closely in single-core performance, with R15 scores tied at 54 and R20 and R23 scores within 1.1%. For a server or workstation where ECC memory is mandatory, the Xeon is the only option of the two, as the Athlon lacks ECC support. The Xeon’s quad-channel memory bus and 51.2 GB/s bandwidth, along with 40 PCIe lanes, make it more expandable in theory, though the benchmarks do not verify any advantage in practice. The Xeon is also end-of-life, while the Athlon is active, so availability and long-term support favor the AMD part. In short, the Athlon wins on performance and efficiency, while the Xeon wins on platform features like ECC and I/O capacity, but the recorded data cannot confirm that those features translate into faster real-world results.

Specification Differences

The two processors differ in nearly every core specification. The Athlon has 2 cores and 4 threads, while the Xeon has 6 cores and 6 threads. Base clocks are 3.50 GHz for the Athlon and 1.90 GHz for the Xeon, and neither chip offers a boost clock. TDP is 35 watts for the Athlon and 85 watts for the Xeon. The Athlon uses AMD Socket AM4, while the Xeon uses Intel Socket 2011-3. Memory support is DDR4 for both, but the Athlon runs dual-channel with 42.7 GB/s bandwidth, while the Xeon runs quad-channel with 51.2 GB/s. ECC memory is not supported on the Athlon but is on the Xeon. PCIe lanes differ dramatically: the Athlon has 8 Gen 3 lanes, while the Xeon has 40 Gen 3 lanes. The Athlon includes integrated Radeon Vega 3 graphics; the Xeon has no integrated graphics. The Athlon’s launch MSRP was $75, while the Xeon’s was $306. The Athlon’s release date is 2018-12-20, while the Xeon’s is 2014-09-07.

Architecture Differences

The architectural gap is wide. The Athlon is built on AMD’s Zen architecture, codenamed Zen and marketed under the Raven Ridge generation, using a 14 nm process from GlobalFoundries. It contains 4,950 million transistors on a die size of 209.8 mm². The Xeon, in contrast, uses Intel’s Haswell architecture, specifically Haswell-EP, on a 22 nm process from Intel’s own fabs. Its transistor count is 2,600 million, with a die size of 356 mm². The cache layouts also differ: the Athlon has 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Xeon has 64 KB of L1 per core, 256 KB of L2 per core, and 15 MB of shared L3 cache. The Xeon’s larger L3 cache is notable, but it does not translate into benchmark wins. The Athlon’s integrated Radeon Vega 3 GPU is absent on the Xeon, and the Xeon’s server-oriented features like ECC and quad-channel memory are not present on the Athlon. The production status also differs: the Athlon is active, while the Xeon is end-of-life. These architectural differences explain why the two chips, despite similar benchmark scores, serve different market segments: the Athlon as a desktop part, the Xeon as a server or workstation part.
