AMD Ryzen 7 5800 vs Intel Core i5-14500T Comparison

Head-to-Head Benchmarks

The benchmark data in this comparison is decisively lopsided. The AMD Ryzen 7 5800 wins 13 of the 17 recorded head-to-head tests, with the Intel Core i5-14500T taking only 4. The margins, however, tell a more nuanced story than the raw win count.

The single largest victory belongs to the AMD processor in Cinebench R23 multi-core, where it scores 21,953 against the Intel's 11,790. That is a 86.2% advantage, a massive gap that dwarfs anything else in the comparison. The single-core variant of the same test shows a 68.6% lead for AMD, with scores of 3,099 versus 1,838. These two results alone establish a clear pattern: in Cinebench workloads, the Ryzen 7 5800 is in a different tier.

Cinebench R20 tells a similar story, though with smaller margins. The AMD chip leads multi-core by 12.8% (9,220 versus 8,177) and single-core by 12.7% (1,301 versus 1,154). Cinebench R15 shows a 9.4% multi-core edge (2,212 versus 2,022) and a 23.8% single-core edge (312 versus 252). The trend is consistent: AMD wins every Cinebench variant, with the single-core gap actually widening in the older R15 test.

PassMark results are more mixed. The Intel processor claims the floating point math test with a score of 58,869 against AMD's 51,588, a 12.4% margin. It also wins the physics test (1,288 versus 1,141, an 11.4% edge) and both single-thread tests, scoring 3,736 versus 3,393, a 9.2% advantage. These wins show that the Intel part has genuine strengths in specific workloads.

But AMD dominates the rest of the PassMark suite. Data compression goes to AMD by 20.6% (316,429 versus 262,417). Data encryption shows a 29.9% lead (20,021 versus 15,410). Extended instructions are 32.7% faster (21,297 versus 16,043). Prime number finding favors AMD by 35.8% (110 versus 81). Integer math goes to AMD by 14.7% (92,843 versus 80,922). Multithread performance favors AMD by 12.7% (25,823 versus 22,910). Random string sorting goes to AMD by 15.9% (32,998 versus 28,462).

The overall average benchmark scores reflect this split. The Intel Core i5-14500T posts an average of 28,065, placing it at the 80th percentile of all CPUs. The AMD Ryzen 7 5800 averages 27,535, at the 79th percentile. Despite winning fewer tests, the Intel part edges out AMD in the aggregate. Its nearest rivals include the AMD Ryzen 5 PRO 8500GE at 28,054 and the Intel Core i9-12900H at 28,003. The AMD Ryzen 7 5800 sits alongside the Intel Core i5-12600K at 27,578 and the AMD Ryzen 7 5700X at 27,578, all within a fraction of a percent of each other.

Architecture Differences

The two processors come from fundamentally different design schools. The AMD Ryzen 7 5800 uses Zen 3 architecture on the Vermeer codename, built on a 7 nm process at TSMC. The Intel Core i5-14500T uses Raptor Lake architecture on the Raptor Lake-R codename, manufactured on Intel's 10 nm process. The process node difference is significant: AMD's 7 nm design allows for a die size of just 74 mm², while Intel's 10 nm part spans 215 mm². AMD packs 4,150 million transistors into that small die area, a remarkable density advantage.

Core counts differ substantially. The AMD chip has 8 cores and 16 threads, all of them full-size performance cores built on a monolithic design, with a boost clock of 4.60 GHz. The Intel part offers 14 cores and 20 threads, mixing performance and efficiency cores, with a higher boost clock of 4.80 GHz. Interestingly, the AMD base clock of 3.40 GHz is nearly double the Intel's 1.70 GHz. The Intel part compensates with more physical cores and a higher boost ceiling, but the AMD design relies on fewer, faster cores with higher base frequencies.

Cache hierarchies also diverge. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB shared L3 cache. Intel counters with 80 KB of L1 per core, 1.25 MB of L2 per core, and a 24 MB shared L3 cache, which is 8 MB less than the AMD chip's L3 allocation. Memory support differs as well: AMD supports DDR4 memory exclusively, while Intel supports both DDR4 and DDR5. AMD's memory bandwidth is rated at 51.2 GB/s, with Intel leaving that field left unrecorded in the database. Both processors support ECC memory, a feature set many desktop users value.

PCIe connectivity shows another distinction. AMD offers Gen 4 PCIe with 20 lanes available from the CPU alone, while Intel provides Gen 5 PCIe with 16 lanes from the CPU. Intel also includes integrated graphics in the form of UHD Graphics 770, whereas AMD lists no integrated graphics at all. The AMD processor has an unlocked multiplier, allowing for overclocking. The Intel processor's multiplier is locked, restricting overclocking options. The AMD part is socketed for AMD Socket AM4, the Intel for Intel Socket 1700, meaning they require entirely different motherboards.

The specification table reveals a clear design philosophy split: the AMD chip uses fewer, faster cores with a high base clock and a larger L3 cache, while the Intel chip offers more cores and threads, a higher boost clock, a lower TDP of 35 W versus 65 W, and integrated graphics. The die size difference is stark, with Intel's 10 nm part nearly three times the physical size of AMD's 7 nm design.

The Verdict

The data points to a clear choice for most workloads: the AMD Ryzen 7 5800 is the stronger performer. It wins 13 of 17 head-to-head tests, and its victories include some of the largest margins in the comparison. The 86.2% lead in Cinebench R23 multi-core and the 68.6% lead in R23 single-core are not close calls; they are dominant results. For users running Cinebench-style rendering or heavily threaded applications that resemble those workloads, the AMD chip is the obvious pick.

The Intel Core i5-14500T is not without merit. It wins the floating point math test by 12.4%, the physics test by 11.4%, and the single-thread PassMark tests by 9.2%. It also posts a higher average benchmark score overall, 28,065 versus 27,535, and sits at the 80th percentile versus AMD's 79th. Its 14 cores and 20 threads outnumber AMD's 8 cores and 16 threads, and its 4.80 GHz boost clock is higher. The Intel part also includes integrated graphics, a feature the AMD chip lacks, and its 35 W TDP is nearly half the AMD's 65 W, making it a more power-efficient option.

However, the aggregate average score difference is only 1.9%, and the AMD chip's benchmark wins are more numerous and often more decisive. The AMD processor also offers an unlocked multiplier, enabling overclocking that the locked Intel part cannot match. Users prioritizing raw performance in the tested workloads should choose the AMD Ryzen 7 5800.

Where Each One Wins

The AMD Ryzen 7 5800 wins in rendering and compute-heavy tasks. Cinebench R15, R20, and R23 multi-core and single-core tests all go to AMD, with margins from 9.4% to 86.2%. PassMark tests covering data compression (20.6% lead), data encryption (29.9% lead), extended instructions (32.7% lead), prime number finding (35.8% lead), integer math (14.7% lead), multithread performance (12.7% lead), and random string sorting (15.9% lead) all favor AMD. This is a processor for users who prioritize heavy computational throughput, encryption, compression, and integer-heavy workloads.

The Intel Core i5-14500T wins in floating point math (12.4% lead), physics simulations (11.4% lead), and single-thread PassMark tests (9.2% lead). These wins suggest strengths in floating point arithmetic and physics-based workloads, as well as lightly threaded applications where its higher boost clock of 4.80 GHz can shine. The Intel chip's integrated UHD Graphics 770 means it can handle display output without a discrete GPU, a practical advantage for basic systems. Its 35 W TDP also makes it a better fit for power-constrained builds, and its support for both DDR4 and DDR5 gives memory flexibility.

The choice ultimately depends on workload priorities. The AMD Ryzen 7 5800 delivers more wins and larger margins across the majority of tests, making it the default recommendation for performance-focused users. The Intel Core i5-14500T offers specific advantages in floating point, physics, and single-threaded PassMark tests, along with integrated graphics and lower power consumption, making it a viable option for users who value those traits. The 86.2% Cinebench R23 multi-core gap is the defining statistic of this comparison, and it overwhelmingly favors AMD.
