AMD Ryzen Threadripper PRO 5945WX vs Intel Core i7-1165G7 Comparison

The AMD Ryzen Threadripper PRO 5945WX and Intel Core i7-1165G7 represent two opposite poles of the processor market: a 280-watt workstation behemoth against a 28-watt mobile chip. The data shows a complete sweep in their shared benchmark suite, with the Threadripper PRO winning all 8 head-to-head tests, yet both processors land at the 65th percentile among all CPUs, suggesting that context matters as much as raw score.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the sheer consistency of the AMD processor’s margin. In Cinebench R15, R20, and R23, the Threadripper PRO 5945WX beats the Core i7-1165G7 by roughly 312% in both single-core and multi-core tests. The multi-core scores tell a predictable story: 3447 versus 835 in R15, 14365 versus 3483 in R20, and 34204 versus 8293 in R23. Each of these represents a deltaPct between 312.4% and 312.8%. The AMD chip’s 12 cores and 24 threads simply overwhelm the Intel part’s 4 cores and 8 threads in any workload that scales with core count.

What is more surprising is that the single-core margins are nearly identical to the multi-core margins. In Cinebench R23 single-core, the Threadripper PRO scores 4828 against the i7-1165G7’s 1170, a 312.6% advantage. This is unusual because Intel’s Tiger Lake architecture was designed for high single-thread performance in thin-and-light laptops. The data suggests that the Threadripper PRO’s 4.50 GHz boost clock, combined with the Zen 3 architecture’s efficiency, delivers a single-thread performance that the 4.70 GHz boost clock of the Intel chip cannot match in these particular tests.

Geekbench shows a slightly different picture. The multi-core gap narrows to 199.3%, with scores of 13371 versus 4467, because Geekbench’s workload mix may not scale perfectly with thread count. However, the single-core Geekbench result is the closest contest in the entire comparison: 2059 versus 1578, a 30.5% advantage for AMD. This is the one benchmark where the Intel chip appears competitive, though it still loses decisively. The overall pattern is unambiguous — the Threadripper PRO 5945WX wins every single benchmark in the shared suite, with margins ranging from a modest 30.5% to a dominant 315.4% in Cinebench R15 single-core.

Where Each One Wins

Based strictly on the benchmark data, the AMD Ryzen Threadripper PRO 5945WX wins everywhere that both processors were tested. There is no benchmark in the shared suite where the Intel Core i7-1165G7 comes out ahead. However, the Intel chip has a broader benchmark portfolio that hints at its intended use case. The i7-1165G7 has 15 benchmark results total, including PassMark tests for data compression (103497), data encryption (5561), extended instructions (7323), find prime numbers (46), floating point math (19830), integer math (33349), multithread (9958), physics (712), random string sorting (12698), and single thread (2763). The Threadripper PRO has only 8 benchmark results, all from Cinebench and Geekbench.

The Intel chip’s additional tests reveal a processor that can handle a variety of everyday tasks, from encryption to sorting, but its scores in these tests are not compared directly to the AMD part because the Threadripper PRO lacks matching benchmarks. The i7-1165G7 also includes 3DMark results (2617 for 16 threads, 1342 for 2 threads, 2015 for 4 threads, 2500 for 8 threads, 2645 for max threads, and 811 for single thread), which the AMD workstation chip does not have in its data set. This suggests the Intel part is more suited to integrated graphics workloads and mobile computing, while the AMD part is designed for server and workstation tasks where raw compute throughput is paramount.

The wins for the Intel chip are therefore implicit rather than explicit. It wins by being the only one of the two with integrated graphics — the Iris Xe-LP Graphics G7 96EU — and by fitting into a 28-watt thermal envelope that allows for laptop deployment. The AMD chip’s 280-watt TDP and AMD Socket WRX8 make such mobility impossible. In terms of benchmark victories, however, the Threadripper PRO 5945WX is the clear winner with 8 wins and 0 losses in the head-to-head comparison.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Threadripper PRO 5945WX uses the Zen 3 architecture, codenamed Chagall PRO, built on a 7 nm process at TSMC. It packs 16,600 million transistors across a die size of 4x 81 mm². The Intel Core i7-1165G7 uses the Tiger Lake architecture, specifically Willow Cove-U, built on Intel’s 10 nm process with a die size of 144 mm². The process node difference — 7 nm versus 10 nm — explains part of the performance gap, as the smaller node allows for more transistors in a similar area.

Cache hierarchies differ significantly. The AMD chip provides 64 KB of L1 cache per core, 512 KB of L2 per core, and a massive 64 MB of L3 cache. The Intel chip offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. While the Intel part has larger per-core L1 and L2 caches, the AMD processor’s 64 MB of L3 is more than five times the Intel chip’s total L3, which likely contributes to its superior performance in cache-sensitive workloads like Cinebench.

The memory architecture is another major divider. The Threadripper PRO supports DDR4 memory over an eight-channel bus with a theoretical bandwidth of 204.8 GB/s, plus ECC memory support. The i7-1165G7 supports DDR4 and LPDDR4X over a dual-channel bus with no listed memory bandwidth and no ECC support. The eight-channel configuration of the AMD part is typical for workstation processors, providing the memory throughput needed for data-intensive applications. PCIe support also differs dramatically: the AMD chip offers Gen 4 with 128 lanes (CPU only), while the Intel chip offers Gen 4 with just 4 lanes (CPU only). This 32-fold difference in PCIe lanes underscores the AMD part’s server/workstation positioning versus the Intel part’s mobile focus.

Specification Differences

The specification table reveals several key differences beyond the obvious core count. The AMD Ryzen Threadripper PRO 5945WX has 12 cores and 24 threads, while the Intel Core i7-1165G7 has 4 cores and 8 threads. Base clocks are 4.10 GHz versus 2.80 GHz, and boost clocks are 4.50 GHz versus 4.70 GHz — the Intel chip actually has a higher boost clock, yet still loses in single-core benchmarks. TDPs are 280 watts versus 28 watts, a 10x difference that reflects the workstation versus mobile design targets.

The sockets are incompatible: AMD Socket WRX8 versus Intel BGA 1449. The AMD part is from the 5000 series with a market segment of Server/Workstation and is still Active in production, while the Intel part has no series designation, targets Mobile, and is End-of-life. Release dates differ by roughly 18 months, with the AMD chip launching on 2022-03-07 and the Intel chip on 2020-09-01. The Intel chip has a launch MSRP of $426, which may be stated once as historical context. Neither processor has an unlocked multiplier, so overclocking is not an option for either. The AMD part’s part number is 100-000000448, while the Intel part’s is SRK02.

The Verdict

The data is unequivocal: the AMD Ryzen Threadripper PRO 5945WX outperforms the Intel Core i7-1165G7 in every shared benchmark, with margins from 30.5% to 315.4%. Any user comparing these two on raw performance alone would choose the AMD part without hesitation. However, these processors are not competing for the same socket, thermal envelope, or market segment. The Threadripper PRO is a Server/Workstation processor with 128 PCIe Gen 4 lanes, eight-channel memory, and a 280-watt TDP, designed for heavy compute workloads where its 12 cores and 64 MB of L3 cache can be fully utilized. The Core i7-1165G7 is an End-of-life mobile processor with integrated Iris Xe graphics, a 28-watt TDP, and 4 PCIe lanes, built for laptops where power efficiency and compactness matter more than raw throughput.

Benchmark results indicate that the AMD processor is the superior choice for workstation and server applications — rendering, scientific computing, and any multithreaded workload. The Intel processor, despite its lower scores, remains the only viable option for mobile computing in this comparison, thanks to its integrated graphics and low power draw. The 65th percentile ranking for both chips, despite the massive performance gap, suggests that the Intel chip’s benchmark portfolio includes tests that favor its architecture, while the AMD chip’s portfolio is narrower. For a buyer choosing between these two, the decision comes down to whether the workload demands the Threadripper PRO’s compute density or the i7-1165G7’s mobility. The benchmark data cannot settle that question — it only shows that in a direct performance contest, the Threadripper PRO wins all 8 head-to-head tests.
