AMD Athlon X4 830 vs Intel Xeon X5470 Comparison

The AMD Athlon X4 830 and the Intel Xeon X5470 are two end-of-life desktop and server processors that deliver nearly identical performance in modern rendering benchmarks. Despite coming from different eras and architectural philosophies, the data shows a remarkably tight contest, with the AMD part securing a narrow but consistent lead across every tested workload. The average benchmark scores place the Athlon X4 830 at 848 and the Xeon X5470 at 839, a difference of roughly 1%, which is well within the margin of noise for most real-world applications but nonetheless consistent across all five Cinebench tests.

Head-to-Head Benchmarks

The head-to-head results are defined by consistency rather than any single dramatic victory. The AMD Athlon X4 830 wins all five benchmark comparisons, yet its largest margin of victory is a modest 1.4%. In Cinebench R15 multi-core, the Athlon scores 248 against the Xeon's 245, a 1.2% advantage. The pattern repeats in Cinebench R20 multi-core, where the Athlon posts 1035 versus 1024, a 1.1% lead. Single-core results follow the same trajectory: the Athlon wins Cinebench R20 single-core with 146 against 144 (1.4% delta) and Cinebench R23 single-core with 348 against 344 (1.2% delta). The smallest gap appears in Cinebench R23 multi-core, where the Athlon's 2465 edges out the Xeon's 2440 by exactly 1.0%.

These are not the kind of numbers that suggest a generational leap. The data indicates two processors that trade blows at the margin, with the AMD chip holding a slight edge in every scenario. Looking at the nearest rivals provides context: the Athlon X4 830 sits between the Intel Xeon X5492 (avg score 852, 0.4% higher) and the Intel Core i5-5250U (avg score 856, 0.9% higher), while also edging out the Intel Core i7-3520M (843, 0.6% lower) and AMD FX-8800P (843, 0.6% lower). The Xeon X5470, meanwhile, is bracketed by the Intel Core i7-920 (840, 0.1% higher) and the Intel Core i5-3380M (838, 0.1% lower), with the Xeon X3450 (837, 0.3% lower) and Core i5-5200U (838, 0.2% lower) trailing slightly. Both processors occupy the 22nd and 23rd percentiles of all CPUs, confirming their position as entry-level performers in the current benchmark landscape.

Where Each One Wins

The benchmark data does not provide a single test where the Intel Xeon X5470 comes out ahead. The Athlon X4 830 wins all five Cinebench iterations, covering both multi-core and single-core workloads. This means the Athlon holds the advantage in rendering tasks that scale with thread count, such as Cinebench R15, R20, and R23 multi-core tests, as well as in lightly-threaded workloads represented by the single-core tests. The largest relative advantage for the AMD part appears in Cinebench R20 single-core at 1.4%, while the smallest is in Cinebench R23 multi-core at 1.0%.

For the Xeon X5470, the "win" is essentially a tie. Its scores are within 1.4% of the Athlon across the board, meaning that in practical use, the differences would be imperceptible. The Xeon's closest benchmark result is in Cinebench R23 multi-core, where it trails by just 25 points. Where the Xeon might be considered to have an edge is not in raw performance but in platform attributes: it supports ECC memory, which the Athlon does not, and it was launched with a server/workstation market position. However, strictly from the benchmark data, the Xeon has zero outright wins.

Architecture Differences

The two processors come from fundamentally different design philosophies and manufacturing eras. The AMD Athlon X4 830 uses the Steamroller architecture on a 28 nm process fabricated by GlobalFoundries, packing 2,411 million transistors into a 245 mm² die. The Intel Xeon X5470 uses the Core 2 architecture (codename Harpertown) on a 45 nm process from Intel, with 820 million transistors spread across two 107 mm² dies. This is a stark contrast in transistor density, with AMD fitting nearly three times as many transistors into a single die that is only slightly larger than one of Intel's two dies.

Cache configurations differ significantly. The Athlon X4 830 has 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache. The Xeon X5470 has 64 KB of L1 cache per core (totaling 256 KB for four cores) and 6 MB of L2 cache per die, which for a dual-die design effectively provides 6 MB per die. Neither processor has L3 cache. Clock speeds favor Intel on paper: the Xeon runs at a base clock of 3.33 GHz with no boost capability, while the Athlon has a 3.00 GHz base clock that boosts to 3.40 GHz. The Athlon's boost clock exceeds the Xeon's fixed clock by 70 MHz, which partially explains its narrow benchmark lead.

Memory support diverges as well. The Athlon uses dual-channel DDR3 with a memory bandwidth of 34.1 GB/s and no ECC support. The Xeon supports dual-channel DDR2 or DDR3 depending on the motherboard, with memory bandwidth not specified in the data, but it does support ECC memory. PCIe generations differ: the Athlon offers PCIe Gen 3 with 16 CPU lanes, while the Xeon provides PCIe Gen 2. The Athlon has an unlocked multiplier, making it overclockable, while the Xeon's multiplier is locked. Power consumption heavily favors AMD: the Athlon has a 65 W TDP versus the Xeon's 120 W TDP. The Xeon was released on September 7, 2008, with a launch MSRP of $1386, while the Athlon's release date and launch MSRP are not specified.

FAQ

Q: Which processor has a higher base clock speed?

A: The Intel Xeon X5470 has a base clock of 3.33 GHz, which is higher than the AMD Athlon X4 830's base clock of 3.00 GHz. However, the Athlon's boost clock reaches 3.40 GHz, exceeding the Xeon's fixed clock.

Q: Do both processors have the same number of cores and threads?

A: Yes, both the AMD Athlon X4 830 and the Intel Xeon X5470 have 4 cores and 4 threads. This means neither processor supports simultaneous multithreading.

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

A: The AMD Athlon X4 830 has an average benchmark score of 848, while the Intel Xeon X5470 scores 839. This places the Athlon 9 points higher, or approximately 1.1% ahead on average.

Q: Which processor supports ECC memory?

A: The Intel Xeon X5470 supports ECC memory, while the AMD Athlon X4 830 does not. This makes the Xeon more suitable for error-sensitive server or workstation workloads.

Q: How do these processors compare in single-core performance?

A: In Cinebench R20 single-core, the Athlon scores 146 against the Xeon's 144, a 1.4% lead. In Cinebench R23 single-core, the Athlon scores 348 versus 344, a 1.2% lead. The Athlon wins both single-core tests by a narrow margin.

Q: What are the process nodes for each processor?

A: The AMD Athlon X4 830 is built on a 28 nm process, while the Intel Xeon X5470 uses a 45 nm process. The smaller process node allows AMD to pack 2,411 million transistors versus Intel's 820 million.

The Verdict

The data points to a clear but narrow victory for the AMD Athlon X4 830. It wins all five benchmark comparisons, holds a higher average benchmark score (848 versus 839), and occupies a slightly better percentile ranking (23rd versus 22nd). The Athlon also offers a lower TDP of 65 W against the Xeon's 120 W, an unlocked multiplier for overclocking, and PCIe Gen 3 support. For anyone building a system where these two are the only options, the Athlon is the better choice on performance, efficiency, and flexibility.

However, the margins are so thin that platform considerations will likely dominate the decision. The Intel Xeon X5470's ECC memory support is a genuine feature that the Athlon lacks, making it the appropriate pick for server or workstation environments where data integrity is critical. The Xeon also has a higher base clock of 3.33 GHz, which may appeal to users who prefer a fixed clock without boost variability. Its launch MSRP was $1386, but that figure has no bearing on current market comparisons.

For a desktop user focused on rendering performance in Cinebench, the Athlon X4 830 is the logical selection. It wins every test, uses less power, and offers overclocking headroom. For a server administrator prioritizing ECC memory and a locked, predictable clock, the Xeon X5470 remains a viable choice despite its slightly lower scores. The benchmark results indicate that neither processor will break any records, but the Athlon is the better overall performer.
