AMD A10-5800B vs Intel Xeon X5482 Comparison

Head-to-Head Benchmarks

The recorded data for these two processors does not include any direct head-to-head benchmark runs, so the comparison must be built from their respective database entries. Looking at the aggregate benchmark scores, the Intel Xeon X5482 posts an average score of 805, while the AMD A10-5800B lands at 794. That is a 1.4% gap in favor of the Xeon, a narrow margin that places both chips in essentially the same performance tier.

The Xeon X5482 has a complete Cinebench record. Its Cinebench R15 multicore score is 235, while the R20 multicore result reaches 983. The R20 single-core score is 138, and the R23 multicore result is 2341 with a single-core score of 330. These numbers show a processor whose multicore scaling is consistent with a quad-core, quad-thread design from its era. The R23 multicore figure is roughly seven times the R23 single-core score, which is expected for a chip with four physical cores and no hyper-threading.

The AMD A10-5800B, by contrast, has only Geekbench entries in the database. Its Geekbench multicore score is 1128, and its single-core score is 459. Without overlapping test suites, a direct apples-to-apples comparison across identical workloads is impossible from the recorded data alone. What can be said is that both processors sit near the 21st to 22nd percentile of all CPUs in the database, with the Xeon at 22 and the A10 at 21. The average scores of 805 and 794 are within 1.5% of each other, and the nearest rival lists confirm this clustering. The Xeon sits within 0.4% of the Intel Core i7-870S and within 0.3% of the Intel Core i5-3320M, while the A10 is within 0.5% of the Intel Core 2 Extreme QX9770.

The Xeon's benchmark results also reveal its age. A Cinebench R23 multicore score of 2341 is modest by modern standards, and its 22nd percentile ranking puts it below the majority of the database population. The A10's 21st percentile is nearly identical, meaning neither chip offers a meaningful overall performance advantage. The delta between the two average scores is small enough that workload-specific behavior, rather than raw compute capability, is likely to be the deciding factor in any real-world comparison.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon X5482 is built on the Core 2 architecture with the Harpertown codename, fabricated on a 45 nm process at Intel's own foundry. It uses 820 million transistors spread across a dual-die package with each die measuring 107 mm², for a combined die size of 214 mm². The AMD A10-5800B uses the Piledriver architecture with the Trinity codename, built on a 32 nm process at GlobalFoundries. It packs 1,303 million transistors onto a single 246 mm² die.

Cache organization differs sharply. The Xeon has 64 KB of L1 cache per core and 6 MB of L2 cache per die, with no L3 cache present. The A10 has 192 KB of L1 cache total and 4 MB of shared L2 cache, also with no L3. The Xeon's per-die L2 arrangement reflects its dual-die construction, while the A10's shared L2 pool is a hallmark of AMD's modular core design. Neither chip has any L3 or 3D V-Cache.

Memory support is another clear split. The Xeon supports DDR2 and DDR3, with the exact type depending on the motherboard, and it runs a dual-channel memory bus. It also supports ECC memory, which aligns with its server and workstation positioning. The A10 supports only DDR3, also on a dual-channel bus, but its memory bandwidth is listed at 29.9 GB/s and it does not support ECC. The Xeon's memory bandwidth figure is not recorded in the database, so a direct bandwidth comparison cannot be made.

Both processors use PCIe Gen 2, and neither has an unlocked multiplier. The Xeon has no integrated graphics, which is typical for a server part. The A10 includes a Radeon HD 7660D integrated GPU, a significant feature difference that gives the AMD chip a display output and basic graphics capability without a discrete card. The Xeon targets the server and workstation segment, while the A10 is a desktop part. The Xeon was released on November 10, 2007, and the A10 followed on October 1, 2012, a gap of nearly five years that explains some of the architectural divergence. Both are end-of-life products.

Where Each One Wins

The Intel Xeon X5482 wins on overall aggregate performance, posting an average score of 805 against the A10's 794. It also holds a slight percentile edge at 22 versus 21. The Xeon's complete Cinebench results, including a Cinebench R23 multicore score of 2341, provide a fuller picture of its multicore capability, and its ECC memory support makes it the appropriate choice for error-sensitive workloads in server or workstation environments. Its DDR2 and DDR3 compatibility adds flexibility for older platforms.

The AMD A10-5800B wins on clock speed, with a base clock of 3.80 GHz and a boost of 4.20 GHz compared to the Xeon's fixed 3.20 GHz. It also wins decisively on power efficiency, drawing 100 watts versus 150 watts for the Xeon. The integrated Radeon HD 7660D GPU is a major practical advantage for a desktop system, eliminating the need for a discrete graphics card in basic display and multimedia scenarios. The A10's newer release date, October 1, 2012, versus November 10, 2007, also means it comes from a more recent design generation with a denser process node.

For use-case selection, the data points to the Xeon for tasks that require ECC memory, server-grade stability, and the higher aggregate compute score. The A10 suits desktop builds where integrated graphics, lower power draw, and higher clock speeds matter more than memory reliability features. The near-identical average scores mean neither chip dominates the other in raw compute; the decision should rest on platform requirements and auxiliary features. The Xeon's 22nd percentile and the A10's 21st percentile confirm that both are entry-level performers in the current database, so expectations for modern workloads should be modest. The Xeon's launch MSRP of $1279 reflects its original server positioning, while the A10's lack of a recorded launch MSRP leaves its pricing history undocumented.
