CPU Comparison

The Intel Xeon E5-1680 v4 and the Intel Core i7-9700F are both eight-core desktop parts, but they come from different eras of Intel’s product stack. The Xeon targets workstation-class platforms with server-derived features, while the i7 is a mainstream consumer chip. Benchmark data shows a consistent, if modest, performance advantage for the older Xeon across all tested Cinebench workloads, despite the i7’s newer architecture and higher boost clock.

Head-to-Head Benchmarks

The Xeon E5-1680 v4 wins all six head-to-head Cinebench comparisons, with margins that are remarkably uniform. In the multi-core tests, the Xeon scores 1,217 points in Cinebench R15 versus 1,126 for the i7-9700F, an 8.1% advantage. That pattern repeats in Cinebench R20, where the Xeon posts 5,073 points against 4,693, and in R23, where it reaches 12,080 versus 11,176. In each case, the delta is exactly 8.1%, indicating that the performance gap scales consistently across render workloads.

The single-core results tell a similar story, though the margins are slightly larger. The Xeon leads by 8.2% in both Cinebench R15 single-core (171 vs. 158) and R20 single-core (716 vs. 662). In R23 single-core, the Xeon’s 1,705 points edge out the i7’s 1,577 by 8.1%. This is notable because the i7-9700F has a substantially higher boost clock of 4.70 GHz compared to the Xeon’s 4.00 GHz, yet the Xeon still wins every single-threaded test. The data suggests that the Xeon’s Broadwell architecture, despite being older, delivers superior instructions-per-clock in these workloads, or that the i7’s higher clock is not translating to proportionally higher performance.

Looking at aggregate performance, the Xeon’s average benchmark score is 3,494, which places it at the 55th percentile of all CPUs. The i7-9700F’s average is 3,464, at the 54th percentile. The difference between the two is less than 1% in aggregate, reinforcing that the Cinebench-specific wins are not indicative of a huge overall performance chasm. The Xeon’s nearest rivals include the Intel Xeon E-2246G (average 3,492, just 0.1% behind) and the Intel Core i9-9900T (average 3,499, 0.2% ahead). The i7-9700F sits near the Intel Xeon E-2186G (3,462, 0.1% behind) and the AMD Ryzen 7 PRO 7730U (3,456, 0.2% behind). These neighbor comparisons show both chips are clustered in a tight performance band, with the Xeon holding a slight edge.

The i7-9700F does have one unique benchmark result not shared by the Xeon: Geekbench scores of 6,807 multi-core and 1,509 single-core. The Xeon’s data set lacks Geekbench entries, so direct comparison on that metric is not possible. Still, for the Cinebench family, the Xeon is the clear winner in every single test, with consistent ~8% margins. The i7’s higher boost clock and newer Coffee Lake architecture do not overcome the Xeon’s combination of 16 threads and larger L3 cache in these workloads.

Architecture Differences

The most significant architectural gap between the two processors is thread count. The Xeon E5-1680 v4 supports Hyper-Threading, offering 8 cores and 16 threads, while the i7-9700F is limited to 8 cores and 8 threads. This doubling of logical processors is a primary reason the Xeon maintains its multi-core lead, even though both chips have the same physical core count.

The process nodes are identical at 14 nm, manufactured by Intel, but the underlying designs differ. The Xeon is based on Broadwell-EP, a server-oriented architecture with a die size of 246 mm² and 3,400 million transistors. The i7-9700F uses Coffee Lake, a refined Skylake derivative, with a smaller die at 180.3 mm² (transistor count not listed). The Xeon’s larger die accommodates its 20 MB of shared L3 cache, whereas the i7 has 12 MB. Both share the same per-core L1 (64 KB) and L2 (256 KB) cache structure, but the Xeon’s 67% larger L3 cache is a meaningful advantage for data-heavy workloads.

Memory support also diverges sharply. The Xeon runs DDR4 in quad-channel mode, delivering 76.8 GB/s of theoretical bandwidth, and supports ECC memory. The i7-9700F uses dual-channel DDR4, with 42.7 GB/s bandwidth, and lacks ECC support. That is a 44% bandwidth deficit for the i7, which can impact memory-intensive applications even if Cinebench does not fully expose it. The Xeon also offers 40 PCIe Gen 3 lanes (CPU only), versus 16 lanes for the i7, making the Xeon far more suitable for multi-GPU or high-expansion configurations.

The sockets are incompatible: the Xeon uses Intel Socket 2011-3, while the i7 uses Intel Socket 1151. The Xeon’s TDP is 140 W, more than double the i7’s 65 W, reflecting its workstation heritage and higher power ceiling. Neither chip has integrated graphics, and both are multiplier-locked. The Xeon was released on 2016-06-19, while the i7 arrived nearly three years later on 2019-04-22. Both are now end-of-life.

Specification Differences

The two chips differ in several key specification fields. The Xeon E5-1680 v4 has 16 threads, while the i7-9700F has 8. Base clocks are 3.40 GHz for the Xeon and 3.00 GHz for the i7; boost clocks are 4.00 GHz and 4.70 GHz, respectively. Thermal design power is 140 W for the Xeon versus 65 W for the i7.

The sockets are distinct: Intel Socket 2011-3 for the Xeon, Intel Socket 1151 for the i7. The Xeon uses the Broadwell-EP architecture (codename Broadwell-EP, generation Xeon E5 Broadwell-EP), while the i7 uses Coffee Lake (generation Core i7 Coffee Lake Refresh). The Xeon’s die size is 246 mm² with 3,400 million transistors; the i7’s die is 180.3 mm² (transistor count not listed). L3 cache is 20 MB shared on the Xeon versus 12 MB shared on the i7.

Memory channels and bandwidth differ: the Xeon supports quad-channel DDR4 at 76.8 GB/s, the i7 dual-channel at 42.7 GB/s. ECC memory is supported on the Xeon only. PCIe lanes are 40 on the Xeon versus 16 on the i7, both Gen 3. The Xeon’s launch MSRP was $1723, while the i7’s was $333. The Xeon released on 2016-06-19; the i7 on 2019-04-22. Both have no integrated graphics, both are locked, and both are end-of-life.

The Verdict

The data is unambiguous on raw performance: the Intel Xeon E5-1680 v4 wins every single Cinebench benchmark in the comparison, with margins between 8.1% and 8.2%. For users running multi-threaded render workloads, the Xeon’s 16 threads and 20 MB of L3 cache deliver a consistent advantage over the i7-9700F’s 8 threads and 12 MB of L3. The Xeon also offers quad-channel memory with ECC support and 40 PCIe lanes, making it the clear choice for workstation-class builds that need memory bandwidth, data integrity, or high expansion capacity.

However, the i7-9700F is not without merit. Its 65 W TDP is less than half the Xeon’s 140 W, which translates to lower power draw and simpler cooling requirements. It sits on the mainstream Socket 1151 platform, which typically means more affordable motherboards and broader compatibility. Its higher boost clock of 4.70 GHz, while not enough to beat the Xeon in Cinebench, still represents strong single-threaded capability for lightly threaded tasks. The i7 also has a lower launch MSRP of $333 versus $1723 for the Xeon, though pricing is not a factor in the benchmark data.

Aggregate scores are nearly identical, with the Xeon at 3,494 and the i7 at 3,464, differing by less than 1%. Neither chip is dramatically better overall; the Xeon’s advantages are specific to multi-threaded, memory-heavy, or ECC-required scenarios. The i7-9700F is the sensible pick for a standard desktop build where power efficiency, platform cost, and high boost clocks matter more than server-grade features. The Xeon E5-1680 v4 is the pick for users who need the extra threads, the quad-channel memory bandwidth, or ECC validation, and who are willing to accept its higher power draw and older platform. Based purely on the benchmark data, the Xeon is the faster processor; based on platform fit and efficiency, the i7 has its place. Choose the Xeon for maximum compute throughput, choose the i7 for a balanced mainstream system.
