AMD A10 PRO-7850B vs Intel Xeon X5482 Comparison

Head-to-Head Benchmarks

The AMD A10 PRO-7850B and Intel Xeon X5482 do not share any common benchmark entries in the database, which makes a direct score-for-score comparison impossible. The recorded data instead places each processor against its own set of nearest rivals, and those comparisons reveal distinct performance profiles. The AMD part averages 828 points across its benchmark suite, while the Intel Xeon averages 805 points, a gap of roughly 2.9 percent in favor of the AMD chip. However, the benchmark compositions differ entirely: the AMD A10 PRO-7850B is measured with Geekbench multicore and singlecore tests, while the Xeon X5482 is evaluated through Cinebench R15, R20, and R23 workloads.

The AMD A10 PRO-7850B's Geekbench multicore score of 1194 positions it above its nearest rivals in the database. Its closest competitor, the Intel Core i5-3360M, averages 835 points, which is 0.8 percent below the AMD part's average of 828. The AMD PRO A10-8750B sits nearly level with 821 points, a 0.9 percent deficit, and the Intel Xeon E5540 matches that same 0.9 percent gap at 820 points. The only rival that edges ahead is the Intel Xeon X3450 at 837 points, a 1.1 percent advantage. In single-core Geekbench, the A10 PRO-7850B records 462 points, a modest figure that reflects its Steamroller architecture's focus on balanced throughput rather than peak single-thread performance.

The Intel Xeon X5482's benchmark results come exclusively from Cinebench iterations. Its Cinebench R15 multicore score of 235 is low by modern standards, but the R20 multicore result of 983 and R23 multicore score of 2341 show scaling across generations of the test. The single-core figures are 138 in R20 and 330 in R23. Against its nearest rivals, the Xeon X5482's average of 805 points ties exactly with the AMD Ryzen 3 2200U at 805 points, a 0 percent delta. The AMD Athlon X4 850 posts 806 points, just 0.1 percent higher, while the Intel Core i5-3320M trails at 803 points, 0.3 percent lower. The Intel Core i7-870S leads this group with 809 points, a 0.4 percent advantage over the Xeon.

Because the two processors were tested with different benchmark suites, no head-to-head wins can be assigned from the recorded data. The database lists zero wins for each part in direct comparison. What the numbers do show is that both chips occupy the same 22nd percentile among all CPUs, indicating they sit at similar overall performance tiers despite their seven-year release gap. The AMD part's average score of 828 versus the Intel part's 805 suggests the newer Kaveri architecture holds a slight edge in the aggregate, but the Xeon's Cinebench results demonstrate respectable multicore throughput for its era.

Architecture Differences

The AMD A10 PRO-7850B is built on the Steamroller architecture, codenamed Kaveri, using a 28 nm process at GlobalFoundries. It integrates 2,411 million transistors on a 245 mm² die. The Intel Xeon X5482 uses the Core 2 architecture, codenamed Harpertown, fabricated on Intel's 45 nm node with 820 million transistors spread across two 107 mm² dies, totaling 214 mm². The process node difference is significant: 28 nm versus 45 nm, which translates into the AMD part's higher transistor density and smaller overall footprint per transistor.

Core and thread counts match at 4 cores and 4 threads for both processors, but clock speeds diverge. The AMD chip runs at a 3.70 GHz base clock with a 4.00 GHz boost, while the Intel Xeon operates at a fixed 3.20 GHz with no boost capability. This gives the AMD part a 0.50 GHz base clock advantage and a 0.80 GHz boost advantage, though the Xeon's older Core 2 architecture often achieved higher instructions per clock in certain workloads during its time.

Cache hierarchies differ substantially. The AMD A10 PRO-7850B has 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache present. The Intel Xeon X5482 offers 64 KB of L1 per core (totaling 256 KB) and 6 MB of L2 per die, for a combined 12 MB of L2 cache across both dies, also without L3. The Xeon's larger L2 allocation could benefit cache-sensitive workloads, though the AMD part's smaller but more modern cache design may reduce latency in other scenarios.

Memory support splits along generational lines. The AMD processor supports DDR3 memory in a dual-channel configuration with a rated bandwidth of 34.1 GB/s, and it does not support ECC memory. The Intel Xeon supports both DDR2 and DDR3 depending on the motherboard, also in dual-channel mode, but the database does not record a bandwidth figure for it. The Xeon does support ECC memory, which aligns with its server and workstation market segment, while the AMD part targets desktop use.

PCIe capabilities also differ. The AMD A10 PRO-7850B provides PCIe Gen 3 with 16 lanes from the CPU, while the Intel Xeon X5482 offers PCIe Gen 2. The AMD part includes integrated Radeon R7 graphics, a feature entirely absent from the Xeon, which relies on a discrete GPU. The AMD chip's socket is AMD Socket FM2+, while the Xeon uses Intel Socket 771. The Xeon's launch MSRP was $1279, a figure recorded in the database, though the AMD part has no recorded launch price.

Where Each One Wins

The AMD A10 PRO-7850B wins in scenarios that favor its higher clock speeds, integrated graphics, and newer process node. Its 4.00 GHz boost clock provides an advantage in lightly threaded tasks where single-core performance matters, such as older games or legacy applications that cannot utilize multiple cores effectively. The Geekbench singlecore score of 462, while not stellar, benefits from the boost capability that the Xeon lacks entirely. The integrated Radeon R7 graphics make the AMD part a self-contained solution for basic display output and light multimedia use, removing the need for a separate GPU. Its 34.1 GB/s memory bandwidth, paired with DDR3 support, offers a clear throughput advantage in memory-intensive workloads compared to the Xeon's unspecified bandwidth.

The Intel Xeon X5482 wins in server and workstation environments where ECC memory support is non-negotiable. Its 12 MB of combined L2 cache provides a larger on-die footprint for data reuse, which can benefit database queries, virtualization hosts, and compute workloads with high cache locality. The fixed 3.20 GHz clock, while lower than the AMD part's base, is consistent and predictable, which matters for long-running server processes where thermal and power variability can affect stability. The Xeon's Cinebench R23 multicore score of 2341 and R20 multicore score of 983 indicate solid multi-threaded rendering performance for its generation, making it viable for batch rendering or scientific calculation tasks that tolerate its higher power draw.

The AMD part's 95 watt TDP versus the Xeon's 150 watt TDP gives the A10 PRO-7850B a clear efficiency advantage. In compact desktop builds or always-on systems, the lower thermal envelope reduces cooling requirements and energy costs over time. The Xeon, with its 150 watt TDP, demands robust cooling and a motherboard designed for high power delivery, which typically confines it to larger chassis or rack-mounted systems.

For mixed-use desktop computing, the AMD A10 PRO-7850B is the more versatile choice due to its integrated graphics, higher clocks, and modern PCIe Gen 3 support. For headless servers or workstations that require ECC memory and maximum cache capacity, the Intel Xeon X5482 holds the edge. The percentile ranking of 22 for both chips confirms they target similar performance tiers, but their architectural priorities diverge sharply: AMD focuses on client-side integration and clock speed, Intel on server reliability and cache depth.
