AMD Ryzen 5 5500GT vs Intel Core i9-11900KF Comparison

Head-to-Head Benchmarks

The recorded data presents a strikingly one-sided comparison. Across all 17 head-to-head benchmark comparisons in the database, the Intel Core i9-11900KF takes the win every single time. The AMD Ryzen 5 5500GT does not claim victory in a single recorded test, and the margin is consistently substantial in Intel's favor.

Starting with rendering workloads, the Intel chip leads by a wide margin. In Cinebench R23 multi-core, the i9-11900KF scores 20,838 against the Ryzen 5 5500GT's 15,848, a 23.9% advantage. The single-core result in the same test shows the Intel part at 2,941 versus 2,237, again a 23.9% delta. The pattern repeats across the older Cinebench versions: R20 multi-core sees the Intel at 8,751 versus 6,656 (23.9% ahead), and R15 multi-core has Intel at 2,100 versus 1,597 (24% ahead). In every Cinebench iteration, the Intel processor holds a lead between 23.9% and 24%.

The PassMark suite tells a similar story, though with some variation in the size of the gap. The largest difference appears in random string sorting, where the Intel part scores 37,383 against 24,583, a 34.2% advantage. Floating point math also shows a big separation: Intel at 52,640 versus AMD at 36,694, a 30.3% lead. Integer math follows at 89,023 versus 64,218, a 27.9% margin. Extended instructions land at 22,703 versus 17,027, a 25% difference, and data compression shows 325,688 versus 243,904, a 25.1% gap.

Some tests show narrower margins. Data encryption is the closest contest in the entire head-to-head set: Intel scores 15,623 against AMD's 14,754, a 5.6% advantage. Single-threaded PassMark results also tighten the gap, with Intel at 3,527 versus AMD at 3,066, a 13.1% lead. Find prime numbers shows Intel ahead by 18.2% (66 versus 54), and physics testing has Intel at 1,034 versus 840, an 18.8% margin. The PassMark multi-thread score lands at 24,708 versus 19,000, a 23.1% delta.

The overall average benchmark scores reinforce this hierarchy. The AMD Ryzen 5 5500GT records an average benchmark score of 26,748, while the Intel Core i9-11900KF sits at 26,212. Interestingly, the AMD part actually holds the higher average score despite losing every direct comparison, which reflects differences in how the aggregate database metrics are weighted across a broader set of tests. The percentile rankings are nearly identical: the AMD processor sits at the 79th percentile among all CPUs, while the Intel chip sits at the 78th percentile. The nearest rivals in the database for the AMD part include the AMD EPYC 9554 (average score 26,743, delta 0%), the Intel Core i7-12700H (26,717, delta 0.1%), and the AMD Ryzen 5 7545U (26,849, delta -0.4%). For the Intel chip, nearby competitors include the AMD Ryzen 5 8540U (26,187, delta 0.1%), the AMD Ryzen 9 6900HX (26,274, delta -0.2%), and the AMD Ryzen 5 8640HS (26,106, delta 0.4%).

The Verdict

The data is unambiguous: the Intel Core i9-11900KF is the faster processor in every head-to-head benchmark recorded. Anyone choosing strictly on performance should select the Intel part. It leads by roughly a quarter in most multi-core workloads, and even in the closest test, data encryption, it remains ahead by 5.6%.

The AMD Ryzen 5 5500GT does have compensating attributes in the database, but they are not performance advantages. It carries a 65 W TDP against Intel's 125 W, and it includes integrated Radeon Vega 7 graphics, which the Intel i9-11900KF lacks entirely. The AMD chip also remains in active production, while the Intel part is listed as end-of-life. The launch MSRP for the AMD part is $125, while the Intel part carries a launch MSRP of $513. Still, the question of which processor wins on raw benchmark output has a single answer: the Intel Core i9-11900KF, and it is not close.

Architecture Differences

The two processors come from fundamentally different design generations and manufacturing approaches. The AMD Ryzen 5 5500GT is built on the Zen 3 architecture, codenamed Cezanne, using a 7 nm process at TSMC. The Intel Core i9-11900KF uses the Rocket Lake architecture on a 14 nm process at Intel's own foundry. The die size reflects this difference: the AMD chip measures 180 mm² with 10,700 million transistors, while the Intel die is larger at 276 mm² with no transistor count recorded in the database.

Core and thread counts differ as well. The AMD part offers 6 cores and 12 threads, while the Intel part provides 8 cores and 16 threads. Clock speeds favor Intel on the boost side: the i9-11900KF boosts to 5.30 GHz from a 3.50 GHz base, while the Ryzen 5 5500GT boosts to 4.40 GHz from a 3.60 GHz base. The AMD chip has the higher base clock, but the Intel chip has the higher boost ceiling by a full 0.90 GHz.

Cache layouts show some similarities and some differences. Both processors have 512 KB of L2 cache per core and 16 MB of L3 cache. The L1 cache differs: the AMD part has 64 KB per core, while the Intel part has 80 KB per core. Memory support is identical in specification: both use DDR4 with dual-channel memory buses and 51.2 GB/s of memory bandwidth. Neither supports ECC memory.

Platform support diverges significantly. The AMD Ryzen 5 5500GT uses AMD Socket AM4 and provides PCIe Gen 3 with 16 lanes from the CPU. The Intel Core i9-11900KF uses Intel Socket 1200 and provides PCIe Gen 4 with 20 lanes from the CPU. The AMD chip includes integrated Radeon Vega 7 graphics; the Intel KF suffix indicates no integrated graphics at all. Both processors have unlocked multipliers, and both target the desktop market segment. The AMD part was released on 2024-01-07, while the Intel part released earlier on 2021-03-15.

Where Each One Wins

The Intel Core i9-11900KF wins everywhere in the recorded benchmarks. There is no test category where the AMD Ryzen 5 5500GT takes the lead. The Intel advantage is largest in random string sorting at 34.2%, floating point math at 30.3%, and integer math at 27.9%. It is smallest in data encryption at 5.6% and single-thread PassMark at 13.1%.

For workloads that stress multi-core rendering, the Intel part is the clear choice. Cinebench R23 multi-core, R20 multi-core, and R15 multi-core all show the Intel chip ahead by roughly 24%. For single-threaded responsiveness, the Intel chip also wins, though the margin narrows to 13.1% in PassMark single-thread testing.

The AMD Ryzen 5 5500GT still has a defined role based on its other characteristics. It offers integrated graphics, a 65 W TDP, and an active production status. For a system that needs a display output without a discrete GPU, or for a build where lower power draw is a priority, the AMD part is the sensible option. The Intel chip cannot output video on its own and draws 125 W. But the question of raw performance is settled: the Intel Core i9-11900KF is the faster processor in every measured category.
