AMD Ryzen Threadripper 9970X vs Intel Core Ultra 7 270K Plus Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen Threadripper 9970X, which wins 9 of the 11 shared benchmark comparisons. The Intel Core Ultra 7 270K Plus claims only 2 wins, both in single-threaded workloads.

The most lopsided result appears in PassMark integer math. The Threadripper 9970X scores 465378 against 175986 for the Ultra 7 270K Plus, a 164.4% advantage. This reflects the massive core-count disparity between the two processors, as the AMD part fields 32 cores with 64 threads while the Intel chip offers 24 cores with 24 threads.

Extended instructions also show a wide gap. The AMD processor delivers 142342 versus 63506 for Intel, a 124.1% lead. Data compression follows a similar pattern: 1757998 for the Threadripper against 804322 for the Ultra 7, a 118.6% difference. Random string sorting shows a 97.5% advantage for AMD, with scores of 191445 and 96945 respectively.

The physics workload, which typically scales with thread count, favors the AMD part by 68.2%. The Threadripper 9970X posts 6835 while the Ultra 7 270K Plus manages 4064. Multithread performance shows a 56.6% gap, with the AMD chip scoring 107399 versus 68574 for Intel.

Data encryption results are closer but still favor AMD. The Threadripper 9970X scores 86765, a 46.8% improvement over the Intel processor's 59097. Floating-point math shows a 35% advantage for AMD: 309719 versus 229491.

The prime number search test is a rare tie. Both processors score exactly 615, indicating that this particular workload does not differentiate between the two architectures despite their different core counts and clock speeds.

The single-threaded tests are the only category where Intel wins. The Ultra 7 270K Plus scores 5068 in PassMark single-thread, which is 10.6% higher than the Threadripper 9970X's 4530. This result appears in both the "passmark_single_thread" and "passmark_singlethread" entries, confirming the consistency of the measurement.

Looking at overall averages, the Threadripper 9970X records an average benchmark score of 279778, while the Ultra 7 270K Plus averages 93785. The AMD processor sits at the 99th percentile among all CPUs in the database, compared to the 96th percentile for the Intel chip.

The nearest rivals in the database provide additional context. The Threadripper 9970X's closest competitor is the Intel Xeon 6780E with an average score of 280438, a delta of -0.2%. The AMD EPYC 9565 scores 285471 (-2%), the Intel Xeon 696X scores 286102 (-2.2%), and the AMD EPYC 9555P scores 287066 (-2.5%).

The Verdict

The benchmark data indicates a clear segmentation between these two processors. The AMD Ryzen Threadripper 9970X is the dominant choice for heavily threaded workloads. Its 32 cores and 64 threads provide overwhelming advantages in integer math, data compression, extended instructions, physics, multithread, floating-point math, random string sorting, and data encryption. The magnitude of these wins, ranging from 35% to 164.4%, demonstrates that the Threadripper is in a different performance class for parallel processing.

The Intel Core Ultra 7 270K Plus offers a single meaningful advantage: single-thread performance. Its 10.6% lead in the PassMark single-thread test, combined with a higher boost clock of 5.50 GHz versus 5.40 GHz for AMD, makes it the better option for lightly threaded applications that depend on raw clock speed.

The database also shows a tie in the prime number search test, meaning neither processor has a distinct edge in that specific workload.

The Threadripper 9970X's average benchmark score of 279778 is approximately 2.98 times higher than the Ultra 7 270K Plus's 93785. The percentile rankings confirm the gap: 99th percentile versus 96th percentile among all CPUs. The nearest rival comparisons reinforce that the Threadripper competes with enterprise Xeon and EPYC parts, while the Ultra 7 sits closer to mid-range server processors.

For users whose workloads scale with core count, the Threadripper 9970X is the clear choice from the recorded data. For users prioritizing single-thread responsiveness and clock speed, the Ultra 7 270K Plus holds the advantage. The launch MSRP for the Threadripper 9970X is $2499, while the Ultra 7 270K Plus has a launch MSRP of $299.

Where Each One Wins

The AMD Ryzen Threadripper 9970X wins in all parallel workloads recorded in the database. This includes data compression (118.6% lead), data encryption (46.8%), extended instructions (124.1%), floating-point math (35%), integer math (164.4%), multithread performance (56.6%), physics (68.2%), and random string sorting (97.5%). These results align with the Threadripper's architecture: 32 cores, 64 threads, 128 MB of L3 cache, and quad-channel DDR5 memory with 204.8 GB/s bandwidth.

The Intel Core Ultra 7 270K Plus wins in single-threaded workloads, posting a 10.6% higher score than the Threadripper. This advantage comes from the higher boost clock of 5.50 GHz and the newer 3 nm process node. The Intel processor also includes integrated Arc Xe-LPG Graphics 64EU, which the AMD part lacks entirely (N/A for integrated graphics).

In the prime number search test, both processors score exactly 615, indicating a dead heat. This workload does not favor either architecture meaningfully.

The use-case split follows directly from these results. Workloads involving heavy parallel computation, such as rendering, video encoding, scientific simulations, data processing, and virtualization, will benefit from the Threadripper 9970X's massive thread count and memory bandwidth. Workloads that are latency-sensitive and single-threaded, such as certain gaming scenarios or legacy applications with limited thread usage, will favor the Ultra 7 270K Plus's higher single-thread score.

The memory subsystem differences reinforce this split. The Threadripper 9970X uses quad-channel DDR5 with 204.8 GB/s bandwidth, while the Ultra 7 270K Plus uses dual-channel DDR5 with 115.2 GB/s. The AMD processor also offers 80 PCIe Gen 5 lanes (CPU only) versus 20 lanes for Intel. Both support ECC memory.
