AMD Ryzen 7 4800U vs Intel Core i5-11400T Comparison

Head-to-Head Benchmarks

The benchmark results split exactly three wins apiece, but the margins tell a more nuanced story than the even win count suggests. The Intel Core i5-11400T and AMD Ryzen 7 4800U each dominate different workloads, with the largest single swing favoring Intel by a massive 32.7% in Cinebench R23 multi-core.

The Intel part's biggest victory comes in Cinebench R23 multi-core, where it scores 11,113 against the AMD's 8,376. That 32.7% advantage is the largest delta recorded across all six head-to-head tests. The same pattern holds in Cinebench R23 single-core: Intel leads 1,569 to 1,235, a 27% margin. These are not marginal differences; they represent a substantial gap in sustained rendering performance and per-thread throughput under the Cinebench R23 workload.

The AMD Ryzen 7 4800U counters strongly in the older Cinebench R15 tests. In Cinebench R15 multi-core, AMD scores 1,411 versus Intel's 1,120, a 20.6% advantage. In Cinebench R15 single-core, AMD leads 183 to 157, a 14.2% margin. The fact that AMD wins the older R15 tests while losing the newer R23 tests by even larger margins suggests the two processors respond very differently to the workload changes between benchmark versions.

Geekbench results are split as well. AMD wins Geekbench multi-core with 6,669 against Intel's 5,591, a 16.2% edge. Intel wins Geekbench single-core with 1,597 versus 1,436, an 11.2% advantage. This split is telling: the AMD chip leverages its additional cores effectively in Geekbench's multi-threaded test, while Intel's single-core architecture holds the advantage in the single-threaded portion.

Looking at the overall averages, the database shows the Intel part with an average benchmark score of 3,309 and the AMD part at 3,218.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i5-11400T uses the Rocket Lake architecture built on Intel's 14 nm process node, with a die size of 276 mm². The AMD Ryzen 7 4800U uses the Zen 2 architecture (codename Renoir) manufactured by TSMC on a 7 nm process, with a much smaller 156 mm² die and 9,800 million transistors.

Core counts differ as well. The Intel part offers 6 cores and 12 threads, while the AMD part provides 8 cores and 16 threads. This two-core, four-thread advantage helps explain AMD's wins in the multi-threaded Geekbench test and Cinebench R15 multi-core, where additional parallel resources can be utilized effectively.

Cache layouts diverge notably. Intel allocates 80 KB of L1 cache per core and 512 KB of L2 cache per core, with 12 MB of shared L3 cache. AMD uses a smaller 64 KB L1 per core but the same 512 KB L2 per core, with only 8 MB of shared L3 cache. The Intel part's larger L3 cache may contribute to its strong Cinebench R23 results, particularly in workloads that benefit from larger shared cache pools.

Memory support shows both similarities and differences. Both processors support DDR4 memory in a dual-channel configuration with 51.2 GB/s of bandwidth. However, the AMD part also supports LPDDR4 memory, reflecting its mobile orientation. Neither processor supports ECC memory.

PCIe capabilities differ substantially. The Intel Core i5-11400T provides PCIe Gen 4 with 20 lanes from the CPU, while the AMD Ryzen 7 4800U is limited to PCIe Gen 3. This gives the desktop Intel platform a bandwidth advantage for storage and discrete graphics expansion.

Integrated graphics also differ. Intel pairs Rocket Lake with UHD Graphics 730, while AMD includes Radeon RX Vega 8 graphics in the Renoir chip. Both are integrated solutions, but they target different performance classes and platform expectations.

The production status tells a story about lifecycle: Intel lists the Core i5-11400T as end-of-life, while AMD lists the Ryzen 7 4800U as active production. The Intel part's release date is March 2021, while the AMD part was released in January 2020.

Specification Differences

The two processors differ across nearly every core specification. The Intel Core i5-11400T operates with a base clock of 1300 MHz and a boost clock of 3.70 GHz. The AMD Ryzen 7 4800U runs at a higher 1800 MHz base clock and boosts to 4.20 GHz. Despite the AMD part's higher clocks, Intel wins single-core tests in the newer benchmarks, indicating that clock speed alone does not determine performance.

Thread counts differ: 12 threads for Intel, 16 for AMD. The core count difference is two cores in AMD's favor. TDP ratings show a significant gap: 35 W for Intel versus 15 W for AMD. This makes the AMD part considerably more power-efficient on paper, though the Intel part's higher power envelope may allow more sustained performance in desktop cooling scenarios.

Socket compatibility is entirely different. The Intel chip uses Intel Socket 1200, while the AMD chip uses AMD Socket FP6. These are not interchangeable platforms. The market segments also differ: Intel targets desktop systems, AMD targets mobile systems.

Process technology separates the two clearly. Intel uses a 14 nm node from its own foundry, while AMD uses TSMC's 7 nm process. The transistor count is only listed for AMD at 9,800 million, and the die sizes are 276 mm² for Intel versus 156 mm² for AMD. The smaller die on the more advanced node gives AMD a density advantage.

Cache specifications differ in L1 and L3. Intel provides 80 KB L1 per core versus AMD's 64 KB per core. Both use 512 KB L2 per core. Intel's shared L3 is 12 MB, while AMD's is 8 MB. Memory support is nearly identical except AMD adds LPDDR4 compatibility.

The integrated graphics differ: Intel uses UHD Graphics 730, AMD uses Radeon RX Vega 8. PCIe support differs with Intel offering Gen 4 and 20 CPU lanes versus AMD's Gen 3. The Intel part has a launch MSRP of $182; the AMD part has no recorded launch MSRP in the database.

Where Each One Wins

The Intel Core i5-11400T wins in modern multi-threaded rendering workloads. Its 32.7% lead in Cinebench R23 multi-core is the standout result, and it also takes Cinebench R23 single-core by 27%. Geekbench single-core also favors Intel by 11.2%. This pattern suggests Intel holds the edge in current-generation rendering workloads and single-threaded applications that benefit from its architecture.

The AMD Ryzen 7 4800U wins in the legacy Cinebench R15 suite and in Geekbench multi-core. Its 20.6% advantage in Cinebench R15 multi-core and 14.2% edge in Cinebench R15 single-core show strength in older benchmark methodologies. The 16.2% Geekbench multi-core win demonstrates that the AMD part's 8-core, 16-thread configuration can outperform the Intel chip when thread scaling is favorable.

For desktop users building a system around modern rendering workloads, the Intel part's Cinebench R23 dominance makes it the stronger choice. The larger 12 MB L3 cache and PCIe Gen 4 support add to its appeal for desktop configurations. The Intel part also offers a higher single-core Geekbench score, which matters for applications with limited thread utilization.

For mobile users or those prioritizing power efficiency, the AMD part's 15 W TDP is a clear advantage over Intel's 35 W. The AMD chip is designed for Socket FP6 mobile platforms, and its 8 cores provide substantial multi-threaded capability in a lower-power envelope. The Geekbench multi-core win also matters for productivity applications that scale well across many threads.

The Verdict

The data does not declare a single winner; it declares two winners for different contexts. The Intel Core i5-11400T leads in the most demanding modern rendering benchmark by a wide margin. Its Cinebench R23 multi-core score of 11,113 versus 8,376 represents the largest performance gap in the entire comparison. For desktop builders prioritizing current-generation rendering performance, the Intel part is the clear choice.

The AMD Ryzen 7 4800U counters with its own compelling case. It offers more cores and threads (8/16 versus 6/12), a dramatically lower TDP (15 W versus 35 W), and wins the Geekbench multi-core test by 16.2%. For mobile platforms where power efficiency and multi-threaded productivity matter, the AMD part holds the advantage. Its active production status also suggests ongoing availability.

Users who run older benchmark-oriented workloads or applications that resemble Cinebench R15's characteristics may prefer the AMD part, given its decisive wins in both R15 tests. Users running modern Cinebench R23-style workloads should strongly favor Intel. The Geekbench split, with AMD winning multi-core and Intel winning single-core, reinforces that neither processor dominates universally.

The average benchmark scores place Intel only 2.8% ahead overall, and both processors sit within one percentile point of each other in the global ranking. This is a close contest between two differently oriented designs. The Intel Core i5-11400T is the desktop performance pick with modern rendering strength. The AMD Ryzen 7 4800U is the mobile efficiency pick with superior thread counts and a much lower power draw. Choose based on platform and workload, not on a single aggregate number.
