AMD Ryzen Threadripper PRO 5945WX vs Intel Core i5-1035G1 Comparison

The Intel Core i5-1035G1 and AMD Ryzen Threadripper PRO 5945WX occupy opposite ends of the computing spectrum: one is a 15 W mobile chip for thin-and-light laptops, the other a 280 W workstation processor. The benchmark data confirms this divide decisively, with the AMD part winning all six head-to-head comparisons. Across the board, the Ryzen Threadripper PRO 5945WX outperforms the Core i5-1035G1 by a consistent margin of 82.3% in every shared test, a rare uniformity that underscores the fundamental performance gap between the two designs. The Intel chip does hold its own in the broader database percentile rankings, matching the AMD part at the 65th percentile among all CPUs, but the raw scores tell a story of complete dominance in compute-heavy workloads.

Head-to-Head Benchmarks

The data is unambiguous. In Cinebench R15 multi-core, the Threadripper PRO 5945WX scores 3447 against the i5-1035G1’s 611, a delta of -82.3% for the Intel part. The single-core R15 test shows the same pattern: 486 versus 86, again a -82.3% difference. This consistency carries through every other benchmark. In Cinebench R20, the AMD chip delivers 14365 multi-core points compared to 2546 for Intel, and 2027 single-core points versus 359. The most recent Cinebench R23 results amplify the gap further: 34204 multi-core for AMD versus 6062 for Intel, and 4828 single-core versus 855.

The 82.3% deficit is identical across all six tests, which is notable. It suggests that the performance ratio between the two chips is nearly constant regardless of workload type, from single-threaded integer work to heavily parallel rendering. The Ryzen Threadripper PRO 5945WX’s 12 cores and 24 threads, combined with its 4.10 GHz base and 4.50 GHz boost clocks, simply overwhelm the 4-core, 8-thread i5-1035G1 with its 1.00 GHz base and 3.60 GHz boost. The Intel chip’s 6 MB of shared L3 cache is dwarfed by AMD’s 64 MB, and the memory bandwidth gap is equally stark: 51.2 GB/s dual-channel versus 204.8 GB/s eight-channel.

Neither chip wins a single head-to-head test. The winsB count is 6, winsA is 0. The data shows no scenario where the Intel part pulls ahead, even in single-threaded tests where smaller, higher-clocked chips sometimes excel. The Threadripper’s 4.50 GHz boost clock is higher than the i5’s 3.60 GHz boost, and its Zen 3 architecture delivers superior instructions per clock. The result is a clean sweep.

Where Each One Wins

The Ryzen Threadripper PRO 5945WX wins every measured category, but the nature of the wins differs by workload. In multi-threaded applications, the advantage is overwhelming. The Cinebench R23 multi-core score of 34204 versus 6062 represents a 5.6x performance advantage, a figure that reflects the 3x core count advantage combined with higher clocks and better architectural efficiency. This makes the AMD chip the clear choice for rendering, simulation, and any workload that scales with thread count.

In single-threaded tasks, the margin narrows but remains substantial. The R23 single-core score of 4828 versus 855 is a 5.6x gap, driven by the higher boost clock and the Zen 3 core design. The Intel chip’s single-core performance is competitive with other mobile processors in its class—its PassMark single-thread score of 2198 places it near the Intel Core i7-3770 and AMD EPYC 7402P in average benchmark score—but it cannot touch the Threadripper’s raw per-core throughput.

The Intel Core i5-1035G1 does have one clear advantage: power consumption. Its 15 W TDP is a fraction of the 280 W TDP of the Threadripper, making it suitable for fanless or low-power designs. It also includes integrated UHD Graphics, whereas the AMD chip has no integrated graphics at all, requiring a discrete GPU. For mobile computing, the i5-1035G1’s 10 nm process and low power draw are decisive. The data shows the Intel chip’s PassMark scores in integer math (26645), floating-point math (15483), and data compression (80534) are respectable for a 4-core mobile part, and its 65th percentile ranking among all CPUs is identical to the Threadripper’s, suggesting that relative to its peers, the i5-1035G1 is not a weak performer.

Specification Differences

The two processors differ in nearly every measurable specification. The Intel Core i5-1035G1 uses an Intel BGA 1526 socket, while the AMD Ryzen Threadripper PRO 5945WX uses AMD Socket WRX8. Core counts are 4 versus 12, and thread counts are 8 versus 24. Base clocks are 1000 MHz for Intel and 4100 MHz for AMD; boost clocks are 3600 MHz and 4500 MHz respectively. The TDP gap is enormous: 15 W versus 280 W.

Memory support is DDR4 for both, but the memory bus differs: dual-channel for Intel, eight-channel for AMD. This yields memory bandwidth of 51.2 GB/s versus 204.8 GB/s. ECC memory support is absent on Intel and present on AMD. PCIe generation differs as well: Gen 3 for Intel, Gen 4 with 128 lanes (CPU only) for AMD. The Intel chip has integrated UHD Graphics; the AMD chip has none. The market segments are Mobile versus Server/Workstation. Release dates are 2019-07-31 for Intel and 2022-03-07 for AMD. Neither chip has an unlocked multiplier.

Architecture Differences

The architectural divide is generational. The Intel Core i5-1035G1 is built on Ice Lake-U architecture with a 10 nm process node manufactured by Intel. Its die size is 123 mm². The AMD Ryzen Threadripper PRO 5945WX uses Zen 3 architecture on a 7 nm process from TSMC, with a die size of 4x 81 mm² and 16,600 million transistors. The cache hierarchies are distinct: Intel uses 80 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3. AMD uses 64 KB L1 per core, 512 KB L2 per core, and 64 MB L3. The Intel part is from the Core i5 (Sunny Cove-U) generation; the AMD part is from the Ryzen Threadripper (Zen 3 Chagall) generation. The codenames are Ice Lake-U for Intel and Chagall PRO for AMD.

The process node difference—10 nm versus 7 nm—explains much of the power and efficiency gap. The Intel chip’s smaller transistor count (not listed) and larger die size relative to performance reflect an older design. AMD’s 7 nm process, combined with 16,600 million transistors across four chiplets, enables higher clocks and greater core density. The L3 cache difference is particularly significant for workstation workloads: 64 MB versus 6 MB provides the Threadripper with substantially more working set capacity for data-intensive tasks.

The Verdict

The choice between these two processors is dictated entirely by use case, and the data makes that clear. The AMD Ryzen Threadripper PRO 5945WX is the correct selection for anyone running multi-threaded professional workloads—rendering, simulation, data analysis—where its 34204 Cinebench R23 multi-core score and 204.8 GB/s memory bandwidth will be fully utilized. The 12 cores, 24 threads, and 64 MB L3 cache are designed for exactly this kind of sustained, parallel compute. Its 280 W TDP is a non-issue in a workstation chassis with adequate cooling.

The Intel Core i5-1035G1 is the right choice for mobile computing where power efficiency is paramount. Its 15 W TDP enables fanless or low-power laptop designs, and its integrated UHD Graphics removes the need for a discrete GPU. Its 6062 Cinebench R23 multi-core score is modest but adequate for office productivity, web browsing, and light content creation. The 65th percentile ranking among all CPUs for both parts indicates that each performs well relative to its own class.

There is no overlap in their target markets. The Threadripper PRO 5945WX is a server/workstation part with ECC memory support, eight-channel memory, and 128 PCIe Gen 4 lanes. The i5-1035G1 is a mobile part with no ECC, dual-channel memory, and Gen 3 PCIe. The benchmark results are not a competition but a confirmation of purpose. If the workload is heavy and parallel, choose AMD. If the requirement is portability and low power, choose Intel. The data supports no other conclusion.
