AMD EPYC 7313P vs Intel Core i9-14900HX Comparison

Head-to-Head Benchmarks

The Intel Core i9-14900HX and AMD EPYC 7313P split the benchmark suite nearly evenly, with Intel taking 11 wins and AMD taking 8. The margins, however, are wildly different in each direction.

The Intel's largest victory is in Geekbench multicore, where it scores 17511 against the EPYC's 10636, a 64.6% lead. The single-core Geekbench result follows the same pattern: 2330 versus 1558, a 49.6% advantage for Intel. These are not small gaps; they represent a generational difference in how the two chips handle bursty, latency-sensitive workloads.

The Intel also dominates in PassMark floating point math, scoring 112273 versus 82260, a 36.5% lead. In PassMark single-thread, it scores 4175 against 2634, a 58.5% advantage. Both of these tests reward the Intel's ability to push a single thread very hard, and the data shows it does so with ease.

In Cinebench R15 multicore, the Intel wins 4574 to 3522, a 29.9% margin. The Cinebench R20 multicore result is closer, with Intel ahead 15616 to 14679, a 6.4% gap. Cinebench R20 single-core also goes to Intel by 6.4%, with scores of 2204 and 2072. PassMark integer math favors Intel by 8.1% (157375 versus 145558), and PassMark multithread favors Intel by 6.5% (43778 versus 41121). Data compression is nearly a tie, with Intel ahead just 2.2% (539965 versus 528167).

The AMD's biggest win is in Cinebench R23 single-core, where it scores 4934 against the Intel's 2181.5, a massive 55.8% lead. This is the single largest delta in the entire head-to-head set, and it flips the expected narrative about which chip is faster per core. Cinebench R23 multicore also goes to AMD, 34952 versus 30055, a 14% lead, showing that the EPYC's 16 Zen 3 cores can outmuscle the Intel's 24-core hybrid design in sustained rendering.

PassMark physics favors AMD by 37.6% (4229 versus 2638), and find prime numbers favors AMD by 44.2% (346 versus 193). Data encryption goes to AMD by 8.7% (35727 versus 32619), extended instructions by 4.7% (32784 versus 31247), and random string sorting by 2.8% (62596 versus 60861). The EPYC also wins Cinebench R15 single-core by 37.5% (497 versus 310.5), a counterintuitive result given that Intel wins the newer R20 single-core test. The data does not fully reconcile these two Cinebench versions, but the pattern suggests the EPYC's Zen 3 cores are strong in certain legacy single-threaded measurements.

Architecture Differences

The Intel Core i9-14900HX is built on Raptor Lake, specifically the Raptor Lake-HX refresh, using Intel's 10 nm process node. It has 24 cores and 32 threads, combining performance and efficiency cores. The base clock is 2.20 GHz with a boost clock of 5.80 GHz. The L1 cache is 80 KB per core, L2 is 2 MB per core, and L3 is 36 MB shared. It supports DDR4 and DDR5 memory in a dual-channel configuration, and it includes integrated UHD Graphics 770. The socket is Intel BGA 1964, and the multiplier is unlocked. The die size is 257 mm².

The AMD EPYC 7313P is a Zen 3 part from the Milan generation, built on TSMC's 7 nm node. It has 16 cores and 32 threads, with a base clock of 3.00 GHz and a boost clock of 3.70 GHz. The L1 cache is 64 KB per core, L2 is 512 KB per core, and L3 is 128 MB shared. It supports DDR4 memory across an eight-channel bus, with a memory bandwidth of 204.8 GB/s. The socket is AMD Socket SP3, and the multiplier is locked. The chip is made of 4x 81 mm² dies, totaling 16,600 million transistors. There is no integrated graphics.

The most striking differences are the cache and memory architecture. The EPYC has nearly four times the L3 cache (128 MB versus 36 MB) and an eight-channel memory bus versus the Intel's dual-channel. The EPYC also has a much higher TDP at 155 watts versus 55 watts, which explains its ability to sustain heavy server loads. The Intel has a much higher boost clock, 5.80 GHz versus 3.70 GHz, which drives its single-thread wins in PassMark and Geekbench. The Intel also supports PCIe Gen 5 with 16 lanes, while the EPYC uses PCIe Gen 4 with 128 lanes.

The Verdict

The data points to two very different machines. The Intel Core i9-14900HX is a mobile processor with an unlocked multiplier and integrated graphics, designed for high-frequency, bursty workloads. It wins 11 of 19 benchmarks, with especially large leads in Geekbench multicore (64.6%), PassMark single-thread (58.5%), and floating point math (36.5%). It also wins Cinebench R15 and R20 multicore, suggesting it handles short rendering bursts well.

The AMD EPYC 7313P is a server and workstation processor with a locked multiplier, no integrated graphics, and a 155-watt TDP. It wins 8 of 19 benchmarks, with huge leads in Cinebench R23 single-core (55.8%) and physics (37.6%). It also wins Cinebench R23 multicore by 14%, which is a stronger indicator of sustained all-core rendering than the older R15 and R20 tests. The EPYC's 128 MB L3 cache and eight-channel DDR4 memory bandwidth make it the better choice for memory-bound server workloads.

If the workload is short, frequency-sensitive, or single-threaded in the PassMark and Geekbench sense, the Intel wins. If the workload is sustained, cache-heavy, or requires massive memory bandwidth, the EPYC wins. The Cinebench R23 results are the clearest tiebreaker for rendering: the EPYC wins both single and multicore there. The Intel's wins in the older Cinebench versions and Geekbench do not erase that.

Where Each One Wins

The Intel Core i9-14900HX wins in Geekbench multicore by 64.6%, in PassMark single-thread by 58.5%, and in floating point math by 36.5%. It also wins Cinebench R15 multicore by 29.9% and R20 multicore by 6.4%. These results point to workloads that benefit from high frequency and bursty execution: desktop-style productivity, single-threaded scripting, and short render or simulation tasks. The unlocked multiplier and integrated graphics also make it a fit for a mobile workstation where flexibility matters.

The AMD EPYC 7313P wins in Cinebench R23 single-core by 55.8%, in physics by 37.6%, and in find prime numbers by 44.2%. It also wins Cinebench R23 multicore by 14%, data encryption by 8.7%, and extended instructions by 4.7%. These wins align with sustained computational loads, especially those that can use the 128 MB L3 cache and eight-channel memory bandwidth. The server socket, 128 PCIe Gen 4 lanes, and 155-watt TDP indicate it is designed for rack-mounted workloads, virtualization, and long-running scientific or database operations.

For a user choosing between them, the decision hinges on the workload's duration and memory pattern. Short, frequency-driven tasks favor the Intel. Long, cache- and bandwidth-hungry tasks favor the AMD. The Cinebench R23 results, which are the most modern render test in the pack, give the edge to the EPYC in both single and multicore, making it the stronger choice for rendering and simulation work. The Intel remains the better pick for general mobile use and single-threaded responsiveness.
