Intel Core i7-9750HF vs Intel Xeon E5-4650 v3 Comparison

The Intel Xeon E5-4650 v3 and the Intel Core i7-9750HF occupy opposite ends of the hardware spectrum, yet their average benchmark scores land within 0.1% of each other (2664 vs 2662). The Xeon is a 12-core, 24-thread Haswell-EP server part designed for socket 2011-3, while the i7 is a 6-core, 12-thread Coffee Lake mobile chip on BGA 1440. The data shows a consistent, if modest, victory for the older Xeon across every Cinebench test, despite its much lower boost clock and older architecture. This is a clash of brute core count versus high-frequency efficiency, and the numbers reveal exactly where each design philosophy pays off.

Head-to-Head Benchmarks

The Xeon E5-4650 v3 wins all six head-to-head benchmark comparisons, but the margins are surprisingly narrow given the hardware disparity. In Cinebench R15 multicore, the Xeon scores 928 against the i7-9750HF’s 876, a 5.9% advantage. The single-core R15 test shows the Xeon ahead by 6.5% (131 vs 123), which is notable because the i7 has a 4.50 GHz boost clock compared to the Xeon’s 2.80 GHz—the older chip’s architecture compensates for the clock deficit.

Moving to Cinebench R20, the pattern holds. The Xeon’s multicore score of 3869 beats the i7’s 3652 by 5.9%, and its single-core score of 546 beats 515 by 6%. The R23 results are nearly identical in percentage terms: the Xeon posts 9212 multicore versus 8696 (5.9% ahead) and 1300 single-core versus 1227 (5.9% ahead). The consistency of these deltas—hovering between 5.9% and 6.5% across all tests—suggests the Xeon’s 12 cores and 24 threads provide a structural advantage that the i7’s higher clocks cannot overcome, even in single-threaded workloads where the i7 should theoretically excel.

The i7-9750HF’s only additional benchmark data comes from Geekbench, where it scores 4844 multicore and 1365 single-core. The Xeon has no Geekbench results in the fact pack, so a direct comparison there is impossible. However, the Cinebench suite is comprehensive enough to establish the Xeon’s lead. The average benchmark scores confirm the near-tie: the Xeon’s 2664 average is just 0.1% above the i7’s 2662, and the Xeon’s nearest rival list includes the i7 with a deltaPct of 0.1%, meaning the two are effectively statistical equals in aggregate performance.

Q: Do both processors support ECC memory?

A: No. The Xeon E5-4650 v3 supports ECC memory, while the i7-9750HF does not. This makes the Xeon suitable for server or workstation reliability requirements, while the i7 is not designed for such use cases.

Q: What is the thermal design power difference?

A: The Xeon E5-4650 v3 has a TDP of 105 watts, while the i7-9750HF has a TDP of 45 watts. The i7 is a mobile chip with lower power draw, but it also has fewer cores and a smaller cache.

Architecture Differences

The architectural divide between these two chips is stark. The Xeon E5-4650 v3 uses the Haswell-EP architecture on a 22 nm process node, manufactured by Intel with 2,600 million transistors on a 356 mm² die. The i7-9750HF uses the Coffee Lake architecture on a 14 nm process node, with a die size of 149 mm² and no transistor count listed. The Xeon’s larger die and older node explain its higher TDP of 105 watts versus the i7’s 45 watts.

Cache configurations also differ sharply. Both have 64 KB of L1 cache per core and 256 KB of L2 per core, but the shared L3 cache is where the Xeon pulls ahead: 30 MB shared versus 12 MB shared on the i7. This 18 MB difference gives the Xeon a substantial pool for caching server-style workloads. The memory subsystem reinforces this: the Xeon uses quad-channel DDR4 with 68.3 GB/s bandwidth, while the i7 uses dual-channel DDR4 with 42.7 GB/s. ECC memory support is exclusive to the Xeon, and it offers 40 PCIe Gen 3 lanes from the CPU, whereas the i7’s PCIe configuration is listed simply as Gen 3 without a lane count.

The Xeon is built for the Intel Socket 2011-3 platform, while the i7-9750HF is a BGA 1440 soldered mobile part. The Xeon’s market segment is Server/Workstation, and the i7’s is Mobile. The Xeon was released on 2015-05-31 with a launch MSRP of $2838, while the i7 was released on 2019-04-22 with no launch MSRP listed. Both are end-of-life and have locked multipliers, so neither offers overclocking headroom.

The Verdict

The data points to a clear, if counterintuitive, conclusion: the older Xeon E5-4650 v3 is the better performer in Cinebench across the board, despite the i7-9750HF’s newer architecture and higher clocks. The Xeon wins all six head-to-head benchmarks, with deltas ranging from 5.9% to 6.5%. Its 12-core, 24-thread configuration and 30 MB of L3 cache overcome the i7’s 6-core, 12-thread setup and 12 MB cache, even in single-core tests where the i7’s 4.50 GHz boost should dominate.

However, the average benchmark scores tell a different story for overall parity. The Xeon’s 2664 average and the i7’s 2662 average are separated by only 0.1%, placing both at the 50th percentile among all CPUs. This means that while the Xeon wins every Cinebench test, the i7 is close enough in aggregate that the choice depends entirely on the use case. The i7’s 45-watt TDP makes it a far more power-efficient option for mobile systems, while the Xeon’s 105-watt TDP, quad-channel memory, and ECC support point to stationary workstation or server duty.

If the workload is multi-threaded rendering or server-style processing, the Xeon’s consistent 5.9% lead in multicore tests and higher memory bandwidth make it the practical pick. If the system needs to be compact, low-power, or mobile, the i7-9750HF is the only viable option given its BGA 1440 socket and 45-watt envelope. The Xeon’s launch MSRP of $2838 also reflects its workstation-class positioning, though the i7 has no listed launch price for comparison.

Specification Differences

The two processors differ in nearly every major specification category. The Xeon E5-4650 v3 has 12 cores and 24 threads, while the i7-9750HF has 6 cores and 12 threads. Base clocks are 2.10 GHz for the Xeon and 2.60 GHz for the i7, but boost clocks flip the script: 2.80 GHz for the Xeon versus 4.50 GHz for the i7. TDP is 105 watts versus 45 watts, respectively. The Xeon uses the Haswell architecture on a 22 nm node, while the i7 uses Coffee Lake on 14 nm. The Xeon’s die is 356 mm² with 2,600 million transistors; the i7’s die is 149 mm² with no transistor count listed.

Cache sizes diverge at the L3 level: the Xeon has 30 MB shared, the i7 has 12 MB shared, with identical 64 KB L1 and 256 KB L2 per core. Memory support is quad-channel DDR4 on the Xeon with 68.3 GB/s bandwidth and ECC support, versus dual-channel DDR4 on the i7 with 42.7 GB/s and no ECC. The Xeon has 40 PCIe Gen 3 lanes from the CPU; the i7 lists only “Gen 3” with no lane count. Sockets are Intel Socket 2011-3 for the Xeon and Intel BGA 1440 for the i7. Market segments are Server/Workstation for the Xeon and Mobile for the i7. The Xeon’s part number is SR22J, and the i7’s is SRG1T.

Where Each One Wins

The Xeon E5-4650 v3 wins every benchmark test in the head-to-head comparison, so its strengths are unambiguous. It is ahead by 5.9% in Cinebench R15, R20, and R23 multicore tests, and by 5.9% to 6.5% in all single-core tests. Its quad-channel memory and 68.3 GB/s bandwidth make it suited for memory-heavy server workloads, and its ECC support adds reliability for data integrity. The 30 MB L3 cache and 40 PCIe Gen 3 lanes further reinforce its workstation credentials.

The i7-9750HF has no benchmark wins against the Xeon, but its competitive average score of 2662 (within 0.1% of the Xeon) and its 45-watt TDP make it the winner for power-constrained or mobile applications. Its 4.50 GHz boost clock, while insufficient to beat the Xeon in Cinebench, indicates higher per-core frequency that could benefit lightly-threaded tasks not covered in the benchmark suite. The dual-channel memory and smaller 149 mm² die also point to a more compact, energy-efficient design. For a laptop or a low-power compact PC, the i7-9750HF is the only choice that fits the socket BGA 1440 form factor, whereas the Xeon demands a full 2011-3 platform with server-grade cooling and power delivery. The data does not show the i7 winning any measured test, but its thermal envelope and mobile platform positioning give it a clear use case that the Xeon cannot serve.
