AMD EPYC 4245P vs AMD Ryzen 7 7700 Comparison

Head-to-Head Benchmarks

The recorded data reveals a split personality between these two AMD parts. The Ryzen 7 7700 wins 9 of the 15 head-to-head benchmark comparisons, while the EPYC 4245P takes 6. That raw win count, however, masks the magnitude of each processor's strengths. The Ryzen 7 7700 dominates throughput-oriented workloads with several decisive victories, while the EPYC 4245P shows its superiority in single-threaded and physics-based tests with equally commanding margins.

Starting with the most dramatic divergence: PassMark extended instructions. The Ryzen 7 7700 scores 96902 against the EPYC's 26547, a 265% advantage. This is the single largest delta in the entire comparison set. The Ryzen 7 7700 also delivers a 155.1% lead in random string sorting, scoring 101836 versus 39916. These two results alone suggest the desktop part has a fundamentally different execution pipeline for specialized instruction workloads and memory-intensive string manipulation.

The Ryzen 7 7700 maintains its advantage in several other PassMark subtests. Data compression shows the desktop chip at 405084 against 339408, a 19.4% edge. Data encryption follows a similar pattern: 23858 versus 18466, good for a 29.2% lead. Integer math comes in at 110295 versus 95120, a 16% delta, while floating point math shows 66246 versus 57965, or 14.3% ahead. The PassMark multithread score also favors the Ryzen 7 7700 at 34470 versus 31063, an 11% difference. Even the find prime numbers test, though close, goes to the Ryzen part: 197 versus 193, a 2.1% margin.

Cinebench results tell a more nuanced story. The Ryzen 7 7700 wins Cinebench R15 multicore with 3047 against 2682, a 13.6% advantage. But in Cinebench R23 multicore, the EPYC 4245P reverses the outcome decisively: 26618 versus 18760, a 29.5% lead for the server chip. This is a notable reversal, suggesting that the longer-duration R23 workload exposes thermal or power characteristics that favor the EPYC's newer architecture.

Single-threaded performance belongs firmly to the EPYC 4245P. In Cinebench R15 single-core, it scores 378 versus 308, an 18.5% lead. Cinebench R23 single-core shows an even larger gap: 3757 versus 1930, a 48.6% advantage. PassMark single-thread mirrors this trend with 4575 versus 4063, an 11.2% edge. The PassMark physics test also goes to the EPYC: 2637 versus 1978, a 25% margin.

The overall average benchmark scores reflect this split. The Ryzen 7 7700 posts an average of 40081, while the EPYC 4245P averages 39215. Both occupy similar percentile positions relative to all CPUs: the Ryzen at 87 and the EPYC at 86. The Ryzen 7 7700's nearest rivals include the AMD Ryzen AI 9 365 with an average score of 40048 (0.1% behind), the Intel Core 5 221E at 40144 (0.2% ahead), the AMD Ryzen 9 270 at 40246 (0.4% ahead), and the Intel Core i9-13905H at 40313 (0.6% ahead). The EPYC 4245P's nearest rivals include the AMD Ryzen 7 PRO 8845HS at 39325 (0.3% ahead), the Intel Core i7-13700F at 39009 (0.5% behind), the AMD Ryzen AI 7 450 at 39485 (0.7% ahead), and the AMD Ryzen 7 PRO 8840HS at 39603 (1% ahead).

The Verdict

The data indicates two distinct use cases. The AMD Ryzen 7 7700 is the choice for workloads that rely on broad multi-threaded throughput across varied instruction types. Its wins in data compression, encryption, extended instructions, integer math, floating point math, and random string sorting show a processor that handles general-purpose computing tasks with consistent efficiency. The 19.4% advantage in data compression and the 29.2% lead in encryption are particularly relevant for file archiving, database operations, and secure communication workloads.

The AMD EPYC 4245P, despite its lower core count, makes a compelling case for single-threaded performance. The 48.6% lead in Cinebench R23 single-core is a massive margin, and the 18.5% advantage in R15 single-core confirms this is not a workload-specific anomaly. The 25% lead in PassMark physics suggests superior mathematical throughput in physics simulation contexts. The EPYC also wins the longer multi-core Cinebench R23 test by 29.5%, which may indicate better sustained performance characteristics under extended load.

For buyers prioritizing maximum single-thread responsiveness or physics simulation capability, the EPYC 4245P is the clear pick. For users running mixed general-purpose workloads, especially those involving data compression, encryption, or string manipulation, the Ryzen 7 7700 offers superior results in the majority of recorded benchmarks. The Ryzen 7 7700 also carries a higher overall average benchmark score (40081 versus 39215) and a slightly better percentile ranking (87 versus 86).

Architecture Differences

The two processors represent different architectural generations. The Ryzen 7 7700 uses Zen 4 architecture with the codename Raphael, fabricated on a 5 nm process at TSMC. The EPYC 4245P uses Zen 5 architecture with the codename Grado, fabricated on a 4 nm process at TSMC. This process shrink is one contributor to the EPYC's single-thread performance advantage.

Transistor counts differ substantially. The Ryzen 7 7700 contains 6,570 million transistors on a 71 mm² die. The EPYC 4245P packs 8,315 million transistors onto a 70.6 mm² die. Despite the similar die size, the EPYC integrates roughly 26.5% more transistors, reflecting the denser 4 nm process and the newer architecture.

Cache hierarchies show notable differences. The Ryzen 7 7700 has 64 KB of L1 cache per core, while the EPYC 4245P has 80 KB per core. Both share 1 MB of L2 per core and 32 MB of shared L3 cache. The larger L1 allocation on the EPYC likely contributes to its single-threaded performance edge.

Both processors support DDR5 memory with dual-channel buses. The Ryzen 7 7700 has a memory bandwidth of 83.2 GB/s, while the EPYC 4245P achieves 89.6 GB/s. Both support ECC memory. PCIe configurations are identical: Gen 5 with 24 lanes from the CPU.

Both parts integrate Radeon Graphics, making them comparable in that regard. The Ryzen 7 7700 has an unlocked multiplier, while the EPYC 4245P does not. The market segments differ: the Ryzen targets desktop, the EPYC targets server and workstation.
