CPU Comparison

# Head-to-Head Benchmarks

The benchmark data is unusually one-sided. Across five Cinebench comparisons, the AMD PRO A10-8750B wins every single test, with margins ranging from 7.8% to 8.1%. This is a consistent, measurable advantage that holds across both single-core and multi-core workloads.

In Cinebench R15 multi-core, the AMD scores 254 against the Intel Xeon X5482's 235, a 8.1% lead. The pattern repeats in R20 multi-core, where the AMD posts 1060 versus 983, a 7.8% edge. Single-core results tell the same story: the AMD's R20 single-core score of 149 beats the Intel's 138 by 8%, and the R23 single-core test shows 356 versus 330, a 7.9% margin.

The largest absolute gap appears in Cinebench R23 multi-core, where the AMD's 2525 exceeds the Intel's 2341 by 184 points. That 7.9% difference is substantial for two processors that share the same core and thread counts. The AMD's highest win percentage (8.1%) comes in the oldest test, R15 multi-core, suggesting the gap is not an artifact of newer benchmark versions.

It is worth noting that the Intel Xeon X5482 has no benchmark wins at all in this comparison. The head-to-head table records 5 wins for the AMD and 0 for the Intel. This is a clean sweep, with no test where the older Xeon manages to pull ahead.

# Where Each One Wins

The AMD PRO A10-8750B wins everywhere that Cinebench measures. Multi-threaded rendering, single-threaded responsiveness, and everything in between favor the AMD part. The data shows a processor that is simply faster across the board in CPU compute workloads.

For the Intel Xeon X5482, the wins are not in raw benchmark scores but in platform characteristics. It supports ECC memory, which the AMD does not. It targets the server/workstation segment, so the intended use case involves reliability and error correction rather than peak performance. The Xeon also carries a launch MSRP of $1279, but pricing is not the focus here.

The AMD counters with integrated Radeon R7 graphics, which the Xeon lacks entirely. For systems that need display output without a discrete GPU, the AMD is the only option of the two. The AMD also supports PCIe Gen 3 with 16 CPU lanes, while the Xeon is limited to PCIe Gen 2.

In terms of production status, both are end-of-life, so neither offers a forward-looking upgrade path. The AMD's release date is later, but that does not translate into benchmark superiority beyond what the scores already show.

# Architecture Differences

The two processors come from different eras and fundamentally different design philosophies. The AMD PRO A10-8750B uses the Steamroller architecture on a 28 nm process from GlobalFoundries, with a die size of 245 mm² and 2,411 million transistors. The Intel Xeon X5482 uses the Core 2 architecture, codenamed Harpertown, on Intel's 45 nm process. Its die is listed as 2x 107 mm², totaling 214 mm², with 820 million transistors.

The AMD is built on a much smaller process node (28 nm versus 45 nm), which typically allows for higher clock speeds and better efficiency. The AMD's base clock is 3.60 GHz with a 4.00 GHz boost, while the Intel runs at a fixed 3.20 GHz with no boost capability. This clock advantage, combined with the architectural generation gap, explains much of the benchmark delta.

Cache configurations differ significantly. The AMD has 256 KB of L1 cache and 4 MB of L2 cache. The Intel has 64 KB of L1 per core and 6 MB of L2 per die. Neither processor has L3 cache. The Intel's larger L2 cache per die does not compensate for its lower clocks and older architecture in these tests.

Memory support also diverges. The AMD uses DDR3 with dual-channel configuration and a memory bandwidth of 34.1 GB/s. The Intel supports DDR2 or DDR3 depending on the motherboard, also dual-channel, but its memory bandwidth is not listed in the data. The Intel supports ECC memory; the AMD does not.

The sockets are incompatible: AMD Socket FM2+ versus Intel Socket 771. The AMD has integrated Radeon R7 graphics, while the Xeon has no integrated graphics. The AMD's PCIe implementation is Gen 3 with 16 lanes from the CPU, whereas the Intel is limited to Gen 2.

# The Verdict

The data is unambiguous. The AMD PRO A10-8750B outperforms the Intel Xeon X5482 in every benchmark recorded. If your priority is raw Cinebench performance, the AMD is the clear choice, with a 7.8% to 8.1% advantage depending on the specific test.

The AMD also brings practical benefits: integrated Radeon R7 graphics, a modern 28 nm process, higher base and boost clocks, and lower TDP at 95 W versus 150 W. It supports PCIe Gen 3, which offers more bandwidth for modern peripherals. For a desktop build where compute performance matters, the AMD is the better part.

However, the Intel Xeon X5482 is not without its own merits. It supports ECC memory, which is a requirement for certain workstation and server workloads where data integrity is paramount. It targets the server/workstation market segment, so it was designed for reliability in sustained operation. The Intel also has a larger L2 cache per die, though this does not translate into a benchmark win.

The Intel's launch MSRP was $1279, but this is historical data and not relevant to current purchasing decisions. Both processors are end-of-life, so neither offers a future upgrade path. The sockets are incompatible, meaning a system built around one cannot swap to the other without a motherboard change.

The AMD's release date is nearly eight years later than the Intel's, which explains the architectural gap. The Steamroller architecture on 28 nm is simply newer and more efficient than Core 2 on 45 nm. The transistor count of 2,411 million versus 820 million reflects this generational difference.

For most users, the AMD PRO A10-8750B is the better choice. It wins every test, has integrated graphics, runs cooler at 95 W, and supports faster PCIe. The only reason to pick the Intel Xeon X5482 is if you specifically need ECC memory support, which the AMD cannot provide. In that narrow case, the Xeon's server-grade reliability features justify its existence despite the performance deficit.

The benchmark data shows a consistent, repeatable performance gap. The AMD's wins are not flukes or single-test anomalies; they are uniform across five different Cinebench versions and workload types. The verdict is straightforward: choose the AMD for performance, choose the Intel only for ECC memory requirements.
