AMD Ryzen 7 3800XT

The AMD Ryzen 7 3800XT is an 8-core, 16-thread desktop processor from AMD's 3000 series. It uses the Zen 2 architecture with the Matisse 2 codename, built on TSMC's 7 nm process with 3,800 million transistors on a 74 mm² die. The base clock is 3.80, the boost clock is 4.70, and the cache configuration is 64 KB of L1 and 512 KB of L2 per core, plus 32 MB of L3. It targets the AMD Socket AM4 platform with a 105 TDP.

Benchmark Performance

The average benchmark score of 4,811 places the Ryzen 7 3800XT in the 63rd percentile of all CPUs. That ranking means the aggregate result sits above the majority of processors in the database, though a substantial group still scores higher. The nearest rivals show just how compact this performance region is: the Intel Core i9-10900E is 0.1% behind, the Intel Core i5-1250P is 0.2% behind, the Intel Xeon E-2386G is 0.3% behind, and the AMD Ryzen 7 5800HS is 0.3% ahead.

The multi-thread results reveal the processor's core-heavy character. Cinebench R23 multi-core reaches 19,969, Cinebench R20 multi-core reaches 8,386, and Geekbench multi-core reaches 8,561. Cinebench R15 multi-core adds an older data point at 2,012. In 3DMark, the 16-thread score is 6,307 and the max-thread score is 6,294, which are nearly identical outcomes; the 8-thread score of 4,743 and the 4-thread score of 2,795 show the intermediate steps of thread scaling, while the 2-thread score of 1,475 covers lightly loaded situations.

Single-thread performance is also present in the data. Cinebench R23 single-core scores 2,819, Cinebench R20 single-core scores 1,183, Cinebench R15 single-core scores 283, Geekbench single-core scores 1,773, and 3DMark single-thread scores 748. Taken together, the 3800XT is defined by strong multi-thread throughput with a healthy single-thread baseline underneath it.

How It Compares

Against the Intel Core i9-10900E, the 3800XT's average score of 4,811 is 0.1% higher than the rival's 4,807. In aggregate terms this is effectively a tie; the delta is too small to separate the two processors in average performance.

Against the Intel Core i5-1250P, the 3800XT is 0.2% ahead. The i5-1250P's average score of 4,802 is slightly lower, so the direction is positive for the 3800XT, but the margin remains fractional.

Against the Intel Xeon E-2386G, the 3800XT is 0.3% ahead. The Xeon's average score of 4,795 is the lowest among the listed rivals, and this 0.3% edge is the largest advantage the 3800XT holds over any of them.

The only rival ahead is the AMD Ryzen 7 5800HS, with an average score of 4,827. That puts the 5800HS 0.3% above the 3800XT, the exact inverse of the Xeon comparison. All four rivals sit within a very narrow performance band around the 3800XT.

Power and Thermals

The 3800XT carries a 105 TDP, which places it in the conventional desktop processor power envelope. A 105 TDP part does not suggest exotic cooling requirements; the data points to a standard desktop cooling class. The 7 nm process node and 74 mm² die are the physical details behind that figure, and the production status being Active means this is a current desktop product in the data. The thermal behavior is governed by the 105 TDP number, and system designs should account for that class of heat output.

Who Should Consider It

Users with heavily multi-threaded workloads should focus on the Cinebench R23 multi-core score of 19,969, the Cinebench R20 multi-core score of 8,386, and the Geekbench multi-core score of 8,561. These numbers reflect what the 8-core, 16-thread configuration can deliver when all threads are active.

Users with gaming or lightly threaded applications should examine the single-thread and low-thread results. Cinebench R23 single-core at 2,819, Cinebench R20 single-core at 1,183, and 3DMark single-thread at 748 indicate solid single-thread capability. The 3DMark 4-thread score of 2,795 is also relevant for workloads that use a small number of threads.

Office and productivity tasks that use two to four threads line up with the 3DMark 2-thread score of 1,475 and the 4-thread score of 2,795. The Cinebench R15 single-core score of 283 is the oldest single-thread data point. The integratedGraphics field is null, so the processor itself does not provide graphics output.

Platform and Compatibility

The 3800XT is built for AMD Socket AM4. Memory support is DDR4 over a dual-channel interface, with a specified memory bandwidth of 51.2 GB/s. ECC memory is not supported. PCIe Gen 4 is present, giving the platform a modern bus generation for attached devices. The multiplier is unlocked, meaning the CPU's clock behavior can be adjusted on compatible boards. The part number is 100-100000279WOF, the market segment is Desktop, and the production status is Active. As a 3000-series Matisse 2 part, the platform boundary is defined by AM4 and DDR4 support.

Single-Thread vs Multi-Thread Behavior

The benchmark split between single-thread and multi-thread tests is clear. Single-thread scores are 748 in 3DMark, 1,183 in Cinebench R20, 2,819 in Cinebench R23, 1,773 in Geekbench, and 283 in Cinebench R15. Multi-thread scores are 6,307 in 3DMark at 16 threads, 6,294 at max threads, 8,386 in Cinebench R20, 19,969 in Cinebench R23, 8,561 in Geekbench, and 2,012 in Cinebench R15.

The 3DMark 16-thread and max-thread scores are nearly identical, which suggests the 16-thread run already captures the practical multi-thread ceiling for that workload. The 8-thread score of 4,743 sits between the 4-thread and 16-thread results, showing that performance increases as more threads are added. Single-thread performance is not weak, but the processor's larger multi-thread scores are what separate it from lower-core-count designs.
