AMD Ryzen Threadripper 9980X vs Intel Core 5 221E Comparison

Head-to-Head Benchmarks

The benchmark data presents a remarkably one-sided comparison. The AMD Ryzen Threadripper 9980X wins all 17 recorded head-to-head tests, with the Intel Core 5 221E taking zero victories. The margins, however, vary dramatically across workload types, which tells a more nuanced story than a simple win count.

The most extreme gap appears in PassMark extended instructions, where the Threadripper scores 228,959 against the Core 5's 18,216, a delta of 1,156.9%. This suggests the AMD processor's wider execution resources and additional cores provide an overwhelming advantage in workloads that leverage advanced instruction sets. Data compression shows a similarly lopsided result, with the Threadripper at 2,974,534 versus 324,285, a difference of 817.3%. Encryption workloads also heavily favor the AMD part, with scores of 157,137 and 19,205 respectively, a 718.2% gap.

The Cinebench results maintain consistent margins across both single-core and multi-core tests. In Cinebench R23 multi-core, the Threadripper posts 130,529 against the Core 5's 25,933, a 403.3% advantage. Single-core R23 shows the same pattern: 18,427 versus 3,661, again 403.3%. The consistency of these deltas across R15, R20, and R23 suggests the performance relationship scales uniformly with the rendering workload rather than favoring any particular optimization.

PassMark integer math shows the Threadripper at 872,071 versus 117,813, a 640.2% lead, while floating-point math delivers 559,003 against 79,028, a 607.3% gap. Random string sorting reveals a 675% difference, with scores of 292,083 and 37,686. Prime number finding, typically sensitive to core count and memory latency, shows a 344.5% delta (769 versus 173).

The closest contest appears in PassMark single-thread performance. Here the Threadripper scores 4,537 against the Core 5's 4,147, a modest 9.4% advantage. This is the only test where the two processors operate in a similar performance class. The physics workload shows a 258.8% gap (8,001 versus 2,230), while the multithread PassMark test records 141,641 versus 30,510, a 364.2% difference.

The data indicates that the Threadripper's advantage scales with thread utilization. In purely single-threaded work, the two chips are close. As workloads expand to use more cores and memory bandwidth, the AMD part pulls away at an accelerating rate. The average benchmark scores confirm this chasm: the Threadripper averages 321,753 across all recorded tests, while the Core 5 averages 40,144.

Architecture Differences

The two processors sit at opposite ends of the desktop spectrum. The AMD Ryzen Threadripper 9980X uses the Zen 5 architecture on TSMC's 4 nm process, with a die size composed of eight 70.6 mm² chiplets and 66,520 million transistors. The Intel Core 5 221E uses the Bartlett Lake architecture on Intel's 10 nm process, with a single 257 mm² die. The Threadripper's 64 cores and 128 threads dwarf the Core 5's 14 cores and 20 threads.

Clock speeds favor AMD at the top end but not by a wide margin. The Threadripper operates at a 3.20 GHz base and 5.40 GHz boost, while the Core 5 runs at 2.70 GHz base and 5.20 GHz boost. The power envelope tells a different story: the Threadripper carries a 350 W TDP against the Core 5's 65 W. This explains why the AMD part can sustain massive multi-core throughput, but it also indicates significantly higher cooling and power delivery requirements.

Cache organization differs substantially. The Threadripper provides 64 KB of L1 and 1 MB of L2 per core, plus 256 MB of L3. The Core 5 offers 80 KB of L1 and 2 MB of L2 per core, but only 24 MB of shared L3. The AMD chip's total cache capacity is roughly ten times larger, which directly impacts the compression and encryption results seen in the benchmarks.

Memory subsystems diverge as well. The Threadripper supports DDR5 in quad-channel configuration with 204.8 GB/s of bandwidth. The Core 5 supports both DDR4 and DDR5 in dual-channel mode, delivering 89.6 GB/s. The AMD part's bandwidth advantage is 2.3 times the Intel chip's, a factor that becomes critical in memory-intensive workloads.

PCIe connectivity also separates the two. The Threadripper provides 80 Gen 5 lanes from the CPU, while the Core 5 offers 16 Gen 5 lanes. Both support ECC memory, and both target the desktop segment. The Threadripper has no integrated graphics, requiring a discrete GPU, while the Core 5 includes UHD Graphics 730. The Threadripper's multiplier is unlocked, the Core 5's is not.

Socket compatibility reinforces the positioning: the Threadripper uses AMD Socket sTR5, the Core 5 uses Intel Socket 1700. The release dates place the Core 5 in January 2025 and the Threadripper in July 2025. The Intel part carries the part number SRQDVQ659, while the AMD chip is 100-000001593.

The Verdict

The recorded data supports a clear separation of roles. The AMD Ryzen Threadripper 9980X delivers exceptional multi-threaded performance, with every recorded benchmark showing a decisive advantage over the Intel Core 5 221E. The narrowest gap, 9.4% in single-thread PassMark, still favors the AMD chip. For workloads that scale across cores, threads, and memory bandwidth, the Threadripper's 64 cores, 128 threads, 256 MB of L3 cache, and quad-channel DDR5 at 204.8 GB/s create an insurmountable lead.

The Intel Core 5 221E operates in a different performance class entirely. Its 14 cores and 20 threads, 24 MB of L3, and dual-channel memory at 89.6 GB/s place it closer to mainstream desktop processors. Its nearest rivals in the database include the AMD Ryzen 7 7700 with a 0.2% delta, the AMD Ryzen AI 9 365 at 0.2%, the AMD Ryzen 9 270 at -0.3%, and the Intel Core i9-13905H at -0.4%. These are all mid-range to upper-mid-range parts, not workstation-class silicon.

The Threadripper's nearest rivals, by contrast, include the AMD Ryzen Threadripper PRO 9985WX at 0.3% delta, the Intel Xeon 6781P at 2%, the AMD EPYC 9575F at 3.2%, and the AMD EPYC 9734 at 3.6%. This places the Threadripper in the company of server and workstation processors, not desktop chips. The 99th percentile ranking among all CPUs reinforces this positioning, while the Core 5 sits at the 87th percentile.

The power disparity matters for deployment decisions. The Threadripper requires a 350 W TDP cooling solution and likely a dedicated GPU, given the absence of integrated graphics. The Core 5's 65 W TDP, bundled UHD Graphics 730, and dual-channel memory make it suitable for compact systems where space and thermal headroom are constrained. The data does not show the Threadripper winning on efficiency, only on absolute performance.

For users whose workloads cannot use more than a handful of threads, the Core 5's single-thread score of 4,147 versus the Threadripper's 4,537 demonstrates that the gap narrows considerably. The Threadripper still wins, but the 9.4% delta does not justify the platform costs implied by the 350 W TDP and sTR5 socket. For users whose workloads scale across 64 cores, the Threadripper's multi-core advantages, ranging from 258.8% to 1,156.9% depending on the test, leave no contest.

Where Each One Wins

The Threadripper wins every recorded benchmark, so the question becomes which workloads show the most extreme advantages. Extended instructions testing shows the largest gap at 1,156.9%, indicating workloads that use specialized instruction sets benefit enormously from the Zen 5 architecture and its 66,520 million transistors. Data compression at 817.3% and encryption at 718.2% suggest the 256 MB L3 cache and quad-channel memory bandwidth directly accelerate these memory-hungry workloads.

Integer math (640.2%), floating-point math (607.3%), and random string sorting (675%) all show advantages above 600%. These are compute-heavy operations that scale with core count. The Cinebench suite, representing rendering workloads, consistently shows around 403% deltas across all versions and both single and multi-core tests. The physics test shows the smallest multi-core gap at 258.8%, while the multithread PassMark test shows 364.2%.

The Core 5's closest performance comes in single-threaded PassMark testing, where the 9.4% delta suggests that lightly threaded applications, web browsing, office productivity, and legacy software would show only modest differences. The Core 5 also offers integrated graphics, allowing basic display output without a discrete GPU, a capability the Threadripper lacks entirely. Its 65 W TDP and dual-channel memory support indicate suitability for space-constrained builds where the Threadripper's 350 W requirement would be impractical.
