Intel Pentium Gold G7400 vs Intel Xeon D-2799 Comparison

Where Each One Wins

The recorded benchmark data leaves no ambiguity in this matchup. The Intel Xeon D-2799 wins every single head-to-head benchmark in the database, taking all six recorded tests. The Intel Pentium Gold G7400 records zero wins across the entire comparison set. That is a clean sweep, and it defines the use-case split entirely around the Xeon D-2799's dominance.

For multi-threaded workloads, the Xeon D-2799 is in a completely different performance class. The Cinebench R23 multi-core score of 28,723 versus the Pentium Gold's 5,700 shows a workload that scales with core count and thread count. The Xeon D-2799 offers 20 cores and 40 threads, while the Pentium Gold G7400 offers 2 cores and 4 threads. Any rendering, simulation, or compilation task that can use many threads will land firmly in the Xeon D-2799's favor. The data shows a multi-core delta of 80.2% in favor of the Xeon D-2799 across all Cinebench multi-core tests, meaning the Pentium Gold trails by that exact percentage in each recorded instance.

Single-threaded performance also belongs to the Xeon D-2799, though the gap is slightly larger in percentage terms. The Cinebench R23 single-core score of 4,055 versus 804 shows the Xeon D-2799 ahead by 80.2% as well. The Xeon D-2799's boost clock of 3.40 GHz helps explain this edge, as the Pentium Gold has no boost clock listed and runs at a fixed 3.70 GHz. Higher frequency alone does not decide the result, but the Xeon D-2799's architecture and boost capability contribute to its single-core advantage.

The Pentium Gold G7400 does have one domain where it can compete: integrated graphics. The G7400 includes UHD Graphics 710, while the Xeon D-2799 lists no integrated graphics at all. For a desktop system that needs basic display output without a discrete GPU, the Pentium Gold is the only option of the two. However, this is not a benchmark category in the recorded data, so it does not change the performance split. The Xeon D-2799 targets server and workstation deployments where a separate GPU or remote management handles display duties.

Power consumption favors the Pentium Gold G7400 in absolute terms. The G7400 has a TDP of 46 watts, while the Xeon D-2799 draws 129 watts. For low-power embedded or basic desktop tasks, the Pentium Gold is the more efficient choice per watt, but the recorded benchmark scores do not include a performance-per-watt metric. The Xeon D-2799 delivers roughly five times the multi-core score in Cinebench R23 for less than three times the TDP, so efficiency per core is still strong on the server part.

Architecture Differences

The two processors come from different Intel architectures and target different market segments. The Pentium Gold G7400 is built on Alder Lake, specifically the Alder Lake-S die, and belongs to the Pentium Gold generation. The Xeon D-2799 is built on Ice Lake, specifically the Ice Lake-D die, and belongs to the Xeon D generation. Both use a 10 nm process node from Intel, so the manufacturing technology is identical, but the design goals diverge sharply.

Core and thread counts set the biggest architectural gap. The Pentium Gold G7400 has 2 cores and 4 threads, a dual-core design with Hyper-Threading. The Xeon D-2799 has 20 cores and 40 threads, a twenty-core design with simultaneous multithreading. That is a 10x difference in core count and a 10x difference in thread count. The Xeon D-2799's 30 MB of shared L3 cache dwarfs the Pentium Gold's 6 MB shared L3 cache. Both processors list the same L1 cache per core at 80 KB and the same L2 cache per core at 1.25 MB, so the per-core cache hierarchy is consistent, but the total cache pool is much larger on the Xeon.

The base clock speeds differ: the Pentium Gold G7400 runs at 3.70 GHz with no boost clock, while the Xeon D-2799 runs at 2.40 GHz base and boosts to 3.40 GHz. The Pentium Gold's fixed frequency gives it a higher base clock, but the Xeon D-2799's boost capability narrows the single-thread gap. The TDP difference reflects the core count: 46 watts for the Pentium Gold versus 129 watts for the Xeon D-2799.

Memory support separates the two clearly. The Pentium Gold G7400 supports both DDR4 and DDR5 with a dual-channel memory bus. The Xeon D-2799 supports DDR4 only but uses a quad-channel memory bus, and the database lists a memory bandwidth of 102.4 GB/s. The Pentium Gold has no memory bandwidth figure recorded. ECC memory support also differs: the Xeon D-2799 supports ECC, while the Pentium Gold G7400 does not. This makes the Xeon D-2799 suitable for error-correcting memory in server environments.

PCIe generation and lane counts differ as well. The Pentium Gold G7400 lists PCIe Gen 5, while the Xeon D-2799 lists PCIe Gen 4 with 32 lanes on the CPU. The socket types are incompatible: the Pentium Gold uses Intel Socket 1700, and the Xeon D-2799 uses Intel BGA 2579. The Xeon D-2799 is a soldered BGA part, meaning it is not socketed for upgrade, while the Pentium Gold is a desktop socketed processor.

Head-to-Head Benchmarks

The head-to-head data shows six recorded tests, all won by the Intel Xeon D-2799. The delta percentage is consistent at 80.2% in favor of the Xeon across every Cinebench test, both multi-core and single-core. This uniformity indicates that the performance gap is structural, driven by core count and architecture, not by workload-specific quirks.

In Cinebench R15 multi-core, the Xeon D-2799 scores 2,895 against the Pentium Gold's 574. The delta is 80.2%, meaning the Pentium Gold trails by that percentage. In Cinebench R15 single-core, the Xeon scores 408 against 80, again a delta of 80.2%. The single-core gap is nearly identical to the multi-core gap in percentage terms, which is notable because single-core performance usually depends more on clock speed and IPC than on core count.

Cinebench R20 multi-core shows the Xeon D-2799 at 12,063 versus 2,394 for the Pentium Gold, a delta of 80.2%. The single-core R20 test shows 1,703 versus 337, also 80.2%. Cinebench R23 multi-core records 28,723 versus 5,700, and the single-core test records 4,055 versus 804. Every delta is exactly 80.2%, which means the database has normalized the comparison across all six tests. The Xeon D-2799 is consistently about five times faster in raw score terms across both multi-core and single-core Cinebench workloads.

The absolute score deltas are large. In Cinebench R23 multi-core, the Xeon D-2799 leads by 23,023 points. In R20 multi-core, the lead is 9,669 points. In R15 multi-core, the lead is 2,321 points. The single-core deltas are smaller in absolute terms but still decisive: 3,251 points in R23, 1,366 in R20, and 328 in R15. The percentage delta stays constant, but the raw point gaps scale with the test's scoring range.

The Pentium Gold G7400's own benchmark scores put it in context. Its average benchmark score is 8,515, and it sits at the 64th percentile of all CPUs. Its nearest rivals include the Intel Core i5-8265U with an average score of 8,568 and a delta of 0.6%, the Intel Core i5-8250U at 8,577 with a delta of 0.7%, and the Intel Core i7-10510U at 8,580 with a delta of 0.8%. The Xeon D-2799's average benchmark score is 8,308, placing it at the same 64th percentile, with nearest rivals including the Intel Xeon Platinum 8268 at 8,315 and a delta of 0.1%, and the Intel Xeon Gold 5320T at 8,316 with a delta of 0.1%. The percentile parity is unusual given the head-to-head sweep, but the average benchmark scores include different test sets, so they are not directly comparable.

The Verdict

The Xeon D-2799 is the clear choice for any workload that demands processing power. The recorded data shows it winning all six head-to-head benchmarks by a consistent 80.2% margin, and its 20 cores and 40 threads provide the parallel capacity that the 2-core Pentium Gold G7400 cannot match. Server and workstation deployments that need multi-threaded rendering, scientific computing, or database workloads should select the Xeon D-2799. Its ECC memory support, quad-channel memory bus, and 102.4 GB/s memory bandwidth further reinforce its suitability for reliable, memory-intensive environments.

The Pentium Gold G7400 is the appropriate pick only for basic desktop systems where integrated graphics are required. It has UHD Graphics 710, while the Xeon D-2799 has no integrated GPU. If a system needs display output without a discrete graphics card and the workload is light, the Pentium Gold can serve that role. Its 46 W TDP makes it a low-power option, and its Socket 1700 platform allows for a traditional desktop build. However, the benchmark data offers no performance category where the Pentium Gold leads, so any compute task beyond the most trivial will favor the Xeon D-2799.

The average benchmark scores place both processors at the 64th percentile, but that statistic masks the head-to-head reality. The Xeon D-2799's nearest rivals include the Xeon Platinum 8268 and Xeon Gold 5320T, both with average scores within a fraction of a percent. The Pentium Gold's nearest rivals are mobile Core i5 and i7 parts from the U-series, which are far below the Xeon's class. The database records show that the Xeon D-2799 is the dominant processor in this comparison, and the only reason to choose the Pentium Gold G7400 is the integrated graphics or the lower power envelope. For raw performance, the verdict is unambiguous: take the Xeon D-2799.
