AMD Ryzen 7 5800HS vs Intel Core i9-11900T Comparison

The AMD Ryzen 7 5800HS and Intel Core i9-11900T are both 8-core, 16-thread processors with a 35W TDP, but they target different segments: the AMD is a mobile part, the Intel is a desktop part. The benchmark data in the database shows a clear winner across all Cinebench tests, with the AMD taking every head-to-head comparison.

The Verdict

The recorded data leaves no ambiguity: the AMD Ryzen 7 5800HS wins all six head-to-head Cinebench tests against the Intel Core i9-11900T. The margins are consistent, ranging from 7% to 7.2% in favor of the AMD part. In multi-core workloads, the AMD scores 1682 in Cinebench R15, 7009 in R20, and 16690 in R23, while the Intel trails at 1572, 6550, and 15596 respectively. Single-core results follow the same pattern: 237 vs 221 in R15, 989 vs 924 in R20, and 2356 vs 2201 in R23. The AMD also holds a higher average benchmark score of 4827 against the Intel's 4685, and a slightly better percentile ranking of 59 versus 58.

For users who prioritize rendering performance as measured by Cinebench, the AMD Ryzen 7 5800HS is the clear choice. The Intel part does have a higher boost clock of 4.90 GHz compared to the AMD's 4.40 GHz, and it supports PCIe Gen 4, but these advantages do not translate into wins in the benchmark suite recorded here. The Intel Core i9-11900T carries a launch MSRP of $439, but the data does not support a performance-based justification for that price. The AMD is also an active production part, while the Intel is end-of-life, making the AMD the more future-proof option based on the available information.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 5800HS uses the Zen 3 architecture, codenamed Cezanne, fabricated on a 7 nm process at TSMC. The Intel Core i9-11900T uses the Rocket Lake architecture, also codenamed Rocket Lake, on Intel's 14 nm process. The process node difference is stark: 7 nm versus 14 nm, which contributes to the AMD's smaller die size of 180 mm² compared to the Intel's 276 mm². The AMD also lists 10,700 million transistors, while the Intel's transistor count is not recorded in the database.

Cache configurations differ in the L1 tier. The AMD has 64 KB of L1 cache per core, while the Intel has 80 KB per core. Both share 512 KB of L2 per core and 16 MB of L3 cache. Memory support is DDR4 for both, but the AMD offers a higher memory bandwidth of 68.3 GB/s versus the Intel's 51.2 GB/s. The AMD uses a dual-channel memory bus, as does the Intel. Neither supports ECC memory.

The integrated graphics differ: the AMD pairs with Radeon Vega 8, while the Intel uses UHD Graphics 750. The AMD is designed for the AMD Socket FP6, a mobile platform, while the Intel uses Intel Socket 1200 for desktop. The AMD supports PCIe Gen 3, whereas the Intel supports PCIe Gen 4 with 20 lanes (CPU only). The base clock of the AMD is 2.80 GHz, while the Intel's base clock is 1500.00 MHz. The boost clocks are 4.40 GHz for the AMD and 4.90 GHz for the Intel. Both have a 35W TDP.

The release dates are close: the AMD launched on 2021-01-11, and the Intel on 2021-03-15. The AMD is marked as active in production, while the Intel is end-of-life. Neither processor has an unlocked multiplier. The AMD's part number is 100-000000295, and the Intel's is SRKNQ.

Head-to-Head Benchmarks

The head-to-head data covers six Cinebench tests, and the AMD wins every one. In Cinebench R15 multi-core, the AMD scores 1682 against the Intel's 1572, a 7% advantage. The single-core R15 test shows a 7.2% lead for the AMD, with scores of 237 and 221. Moving to Cinebench R20, the AMD's multi-core score of 7009 beats the Intel's 6550 by 7%, and the single-core score of 989 beats 924 by 7%. Cinebench R23 follows the same pattern: the AMD's multi-core score of 16690 is 7% higher than the Intel's 15596, and the single-core score of 2356 is 7% higher than 2201.

These consistent deltas indicate that the AMD's architectural efficiency, likely stemming from the 7 nm process and higher memory bandwidth, gives it a uniform advantage across different Cinebench versions. The Intel's higher boost clock of 4.90 GHz does not overcome the AMD's per-clock performance. The database also includes Geekbench scores for the Intel (multi-core 8257, single-core 2157), but no corresponding Geekbench results for the AMD, so a direct comparison in that benchmark is not possible from the recorded data.

The AMD's average benchmark score of 4827 places it slightly above its nearest rivals, including the AMD Ryzen 7 4700GE (4836, delta -0.2%), the AMD Ryzen 9 3950X (4807, delta 0.4%), the Intel Xeon E-2386G (4799, delta 0.6%), and the Intel Core i5-1350P (4776, delta 1.1%). The Intel Core i9-11900T's average score of 4685 sits near its own rivals: the Intel Core i9-10900F (4664, delta 0.5%), the Intel Core i9-10900E (4708, delta -0.5%), the Intel Core i9-9900KF (4652, delta 0.7%), and the Intel Core i7-6950X (4734, delta -1%). These figures show that the AMD is not only ahead of the Intel in direct comparison but also holds a higher position in the overall performance distribution.

Where Each One Wins

The AMD Ryzen 7 5800HS wins every Cinebench test recorded in the head-to-head comparison. This makes it the stronger choice for multi-threaded rendering workloads, such as video encoding, 3D modeling, and batch image processing, where Cinebench scores are indicative of performance. The AMD also leads in memory bandwidth (68.3 GB/s vs 51.2 GB/s) and uses a smaller, more efficient 7 nm process. Its active production status means it remains available for new systems, whereas the Intel is end-of-life.

The Intel Core i9-11900T does have some advantages in the specification sheet. Its boost clock of 4.90 GHz is higher than the AMD's 4.40 GHz, which could benefit lightly threaded tasks that rely on single-core frequency, though the Cinebench single-core tests show the AMD still wins by 7% or more. The Intel also supports PCIe Gen 4 with 20 lanes, which is useful for high-speed storage and graphics cards, while the AMD is limited to PCIe Gen 3. The Intel's larger L1 cache (80 KB per core vs 64 KB) may help in certain cache-sensitive workloads, but the recorded benchmarks do not reflect a performance advantage. The Intel is a desktop part, which means it fits into standard desktop motherboards with Socket 1200, while the AMD is a mobile part for Socket FP6, limiting its use to laptops or compact systems.

For users building a desktop with PCIe Gen 4 devices, the Intel Core i9-11900T offers that connectivity, but the benchmark data shows the AMD outperforms it in all Cinebench tests. The AMD's higher average score and percentile ranking reinforce its overall performance lead. The Intel's launch MSRP of $439 is noted, but the performance data does not show a corresponding benefit. In summary, the AMD Ryzen 7 5800HS is the better performer in the recorded benchmarks, while the Intel Core i9-11900T retains niche advantages in platform features and clock speed.
