AMD A10 PRO-7800B vs Intel Xeon E5450 Comparison

Head-to-Head Benchmarks

The recorded data shows that these two processors do not share any direct benchmark tests in the database. The Intel Xeon E5450 was measured across the Cinebench suite, while the AMD A10 PRO-7800B was measured with Geekbench. This lack of overlap makes a direct apples-to-apples comparison impossible from the collected results alone. However, the aggregate average benchmark scores provide a useful starting point.

The Intel Xeon E5450 posts an average benchmark score of 756, while the AMD A10 PRO-7800B sits at 746. That is a 10-point gap, roughly 1.3% in favor of the Intel part. In percentile terms, both processors land at the 20th percentile among all CPUs in the database, meaning they occupy the same overall performance tier. The nearest rivals for the Xeon E5450 include the Intel Core i5-4250U (matching score of 756, 0% delta), the Intel Core i3-5020U (757, -0.2% delta), the Intel Core i5-3230M (754, 0.2% delta), and the Intel Core i5-3210M (758, -0.2% delta). The AMD A10 PRO-7800B's nearest rivals are the Intel Core i5-4200U (746, 0% delta), the AMD FX-9800P (745, 0.1% delta), the Intel Core i5-750 (747, -0.2% delta), and the Intel Xeon E5520 (742, 0.6% delta).

Looking at the individual Cinebench results for the Xeon E5450, the multicore scores are 221 (Cinebench R15), 923 (Cinebench R20), and 2198 (Cinebench R23). The single-core scores are 130 (Cinebench R20) and 310 (Cinebench R23). These numbers place the Xeon firmly in entry-level territory for modern rendering workloads. The AMD A10 PRO-7800B's Geekbench results show a multicore score of 1055 and a single-core score of 436. While these are different test suites, the Geekbench single-core figure suggests the AMD part has a significant per-thread advantage, which aligns with its higher base clock.

The Xeon E5450 has a base clock of 3.00 GHz with no boost clock listed, while the AMD A10 PRO-7800B runs at 3.50 GHz base and boosts to 3.90 GHz. That is a 0.50 GHz base clock advantage and a 0.90 GHz boost advantage for the AMD chip. In single-threaded workloads, the AMD part should theoretically outperform the Intel part by a substantial margin, though the lack of shared benchmarks prevents a direct confirmation. For multicore workloads, the Xeon's larger cache hierarchy (6 MB L2 per die versus 4 MB L2 for the AMD) may help compensate for its lower clock speed.

The average benchmark scores tell a story of near-parity. With the Xeon at 756 and the AMD at 746, the difference is within the margin of error seen in the nearest rival comparisons. Both chips sit at the 20th percentile, meaning neither is a standout performer in the broader CPU landscape. The data implies that the choice between these two hinges on workload-specific factors rather than overall performance dominance.

The Verdict

The data does not declare a clear winner. The Intel Xeon E5450 holds a slight edge in aggregate average benchmark score (756 versus 746), but the AMD A10 PRO-7800B counters with a higher base clock (3.50 GHz versus 3.00 GHz) and a boost clock (3.90 GHz) that the Xeon lacks entirely. For users prioritizing raw single-thread responsiveness, the AMD part has the clock speed advantage. For users prioritizing cache capacity, the Xeon's 6 MB L2 per die versus the AMD's 4 MB L2 gives Intel the edge in data-heavy workloads.

The Xeon E5450 targets the server and workstation market segment, while the AMD A10 PRO-7800B is a desktop part. This difference matters for platform considerations. The Xeon uses Intel Socket 771, while the AMD part uses AMD Socket FM2+. The Xeon supports ECC memory, a feature absent on the AMD chip. The AMD part includes integrated Radeon R7 graphics, which the Xeon lacks entirely. For a system that needs error-correcting memory or server-grade reliability, the Xeon is the only choice. For a desktop build that wants a single-chip solution with graphics, the AMD part is the only choice.

The production status for both is end-of-life, so neither is a new purchase. The Xeon E5450 launched in November 2007, while the AMD A10 PRO-7800B launched in July 2014. The AMD part is roughly seven years newer, which explains its smaller process node (28 nm versus 45 nm) and higher transistor count (2,411 million versus 820 million). The Xeon's launch MSRP was $915, though this figure should not be interpreted as current value, only as a historical data point.

Where Each One Wins

The AMD A10 PRO-7800B wins on clock speed. Its 3.50 GHz base clock and 3.90 GHz boost clock are both higher than the Xeon's fixed 3.00 GHz. In single-threaded tasks that rely on frequency, the AMD part should deliver faster response times. The Geekbench single-core score of 436 supports this, though without a matching Cinebench single-core score for the AMD chip, the comparison remains indirect.

The AMD part also wins on platform features for desktop users. It includes integrated Radeon R7 graphics, eliminating the need for a separate graphics card. It supports PCIe Gen 3 with 16 lanes, while the Xeon uses PCIe Gen 2. The AMD chip has a lower TDP of 65 watts versus the Xeon's 80 watts, making it easier to cool in a compact desktop system.

The Intel Xeon E5450 wins on cache. Its L1 cache is 64 KB per core, while the AMD part has 256 KB total L1. The Xeon's L2 is 6 MB per die, while the AMD part has 4 MB total L2. For workloads that repeatedly access large datasets, the Xeon's larger cache can reduce memory latency and improve throughput. The Xeon also supports ECC memory, which is critical for servers and workstations where data integrity is paramount.

The Xeon wins on memory flexibility. Its memory support is listed as DDR2 or DDR3 depending on the motherboard, while the AMD part supports only DDR3. This gives the Xeon more options for legacy systems. The Xeon also has a higher average benchmark score (756 versus 746), though the margin is small.
