AMD Ryzen 7 9800X3D vs AMD Ryzen AI 7 445 Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep. The AMD Ryzen 7 9800X3D wins all 15 head-to-head benchmark comparisons, with zero wins for the AMD Ryzen AI 7 445. The margins are not subtle. In PassMark's find prime numbers test, the desktop part posts a score of 423 against 56, a delta of 655.4%. That is the largest relative gap in the entire comparison set.

Multi-core workloads show the expected pattern. Cinebench R23 multicore scores 23230 for the 9800X3D versus 10590 for the 445, a 119.4% advantage. Cinebench R15 multicore follows with 3647 against 1723, a 111.7% delta. PassMark multithread delivers 40009 versus 18115, a 120.9% difference. The desktop chip has roughly double the raw throughput in every heavily threaded test.

Single-core results are closer but still decisive. Cinebench R23 singlecore shows 2080 against 1806, a 15.2% lead. PassMark single thread records 4430 versus 3591, a 23.4% delta. Cinebench R15 singlecore shows 328 against 254, a 29.1% gap. The smallest margin in the entire dataset is the 15.2% single-core R23 result, but it still favors the 9800X3D without exception.

Specialized workloads amplify the gap further. PassMark extended instructions scores 38808 versus 15826, a 145.2% delta. PassMark physics records 4083 versus 976, a 318.3% difference. Data compression shows 468017 against 215812, a 116.9% margin. Encryption delivers 22158 versus 10519, a 110.6% gap. Floating point math reaches 79456 against 39362, a 101.9% lead. Integer math follows at 116709 versus 58332, a 100.1% delta. Random string sorting completes the pattern with 48526 versus 23488, a 106.6% advantage.

Where Each One Wins

The 9800X3D wins everywhere in this comparison. There is no benchmark category where the 445 records a higher score. However, the meaning of that sweep depends on context. The 9800X3D sits in the 87th percentile of all CPUs in the database, with an average benchmark score of 39768. The 445 sits in the 79th percentile with an average score of 26936. Both are above the midpoint, but the desktop part occupies a clearly higher performance tier.

For the 9800X3D, the strongest absolute results appear in multi-threaded and math-heavy tasks. PassMark integer math at 116709, floating point math at 79456, and multithread at 40009 all rank among its highest recorded outputs. The Cinebench R23 multicore score of 23230 reinforces that strength. These numbers indicate a processor that handles sustained parallel workloads with substantial headroom.

For the 445, the best results are its single-core figures. PassMark single thread at 3591 and Cinebench R23 singlecore at 1806 are respectable on their own. But even those are 15.2% and 23.4% behind the 9800X3D respectively. The 445's PassMark multithread score of 18115 is roughly half the 9800X3D's 40009, and its Cinebench R23 multicore of 10590 is less than half of 23230. The mobile chip does not close the gap in any workload category.

The nearest rival data reinforces the positioning. The 9800X3D's closest competitors include the AMD Ryzen 7 PRO 8840HS at 39603 (0.4% delta), the AMD Ryzen AI 9 365 at 40048 (-0.7% delta), the AMD Ryzen AI 7 450 at 39485 (0.7% delta), and the AMD Ryzen 7 7700 at 40081 (-0.8% delta). These are all near its average score. The 445's nearest rivals include the Intel Core i7-1370P at 26900 (0.1% delta), the AMD Ryzen 5 7545U at 26849 (0.3% delta), the AMD Ryzen 7 5700G at 27051 (-0.4% delta), and the Intel Core i9-9900K at 27097 (-0.6% delta). The two CPUs operate in entirely different performance neighborhoods.

Architecture Differences

The two processors share a Zen 5 architecture and a 4 nm process node from TSMC, but the similarities end there. The 9800X3D uses the Granite Ridge codename and belongs to the 9000 series. The 445 uses the Gorgon Point codename and belongs to the Ryzen AI 400 series. The desktop part has 8 cores and 16 threads, while the mobile part has 6 cores and 12 threads.

Cache configuration differs drastically. The 9800X3D carries 80 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3. The 445 also has 80 KB of L1 per core and 1 MB of L2 per core, but only 4 MB of L3 total. That 96 MB versus 4 MB L3 gap is the single largest architectural difference and explains much of the performance delta in cache-sensitive workloads.

Clock speeds tell a similar story. The 9800X3D has a base clock of 4.70 GHz and a boost clock of 5.20 GHz. The 445 has a base clock of 2.00 GHz and a boost clock of 4.60 GHz. The desktop part runs at more than double the base frequency. Power envelopes differ accordingly: the 9800X3D has a 120 W TDP, while the 445 has a 28 W TDP.

The sockets are incompatible. The 9800X3D uses AMD Socket AM5, a desktop platform. The 445 uses AMD Socket FP8, a mobile platform. The 9800X3D offers PCIe Gen 5 with 24 CPU lanes, while the 445 offers PCIe Gen 4 with 14 CPU lanes. Both support dual-channel DDR5 memory with 89.6 GB/s bandwidth and ECC memory. The 9800X3D lists Radeon Graphics as its integrated GPU, while the 445 lists Radeon 840M. The 9800X3D has an unlocked multiplier; the 445 does not. The desktop part has a launch MSRP of $479; the mobile part has no recorded launch MSRP.

Production status is active for both. The 9800X3D released on 2024-11-06, while the 445 lists a release date of 2026-01-04. The 9800X3D uses 8,315 million transistors on a 70.6 mm² die. The 445 has no recorded transistor count or die size in the database.

The Verdict

The data supports a clear split based on usage context. The 9800X3D is the stronger processor in every recorded benchmark. Its 15 wins out of 15 comparisons, combined with an 87th percentile ranking and an average score of 39768, place it firmly in the high-performance desktop tier. The 445, with zero wins and a 79th percentile ranking, is a mobile part designed for lower power consumption.

For workloads that demand maximum throughput, the 9800X3D is the obvious choice. Its 96 MB L3 cache, 8 cores, 16 threads, and 5.20 GHz boost clock produce scores roughly double those of the 445 in multi-threaded tests. The 120 W TDP is the cost of that performance, and the AM5 socket requires a desktop motherboard.

The 445 serves a different purpose. Its 28 W TDP and FP8 socket indicate a mobile processor for laptops. Its 6 cores and 12 threads are fewer, and its 4 MB L3 is minimal by comparison. The 2.00 GHz base clock reflects a power-saving design. Users who prioritize battery life and portability over raw compute will find the 445's profile appropriate, but the benchmark data shows it cannot match the 9800X3D in any measured category.

The nearest rival comparisons confirm the separation. The 9800X3D competes with desktop and high-end mobile parts like the Ryzen 7 7700 and Ryzen AI 9 365. The 445 competes with older and lower-power parts like the Core i7-1370P and Ryzen 7 5700G. These are different leagues, and the head-to-head results simply reflect that.
