Intel Core i7-11700B vs Intel Xeon E5-2699A v4 Comparison

The Intel Xeon E5-2699A v4 and the Intel Core i7-11700B occupy opposite ends of the design spectrum, yet their aggregate benchmark scores place them nearly on top of each other. The Xeon is a 22-core Broadwell-EP server part from 2016, while the Core i7 is an 8-core Tiger Lake-H mobile processor from 2021. Despite the massive difference in core counts and physical scale, the average benchmark score difference between them is a razor-thin 0.4% in favor of the Xeon (5259 vs 5241). This creates an unusual comparison where the older, larger, and more expensive part essentially trades blows with a newer, smaller, and more efficient one in synthetic workloads.

Where Each One Wins

The benchmark data is unambiguous in its single-core and multi-core split, even if the margins are small. The Intel Core i7-11700B wins every single head-to-head benchmark recorded, taking all six tests in the comparison set. Its victories in Cinebench R15, R20, and R23 single-core tests are consistent, posting margins of -1.6% to -1.7% relative to the Xeon. This indicates that the Core i7's newer architecture, higher base clock of 3.20 GHz, and boost clock of 4.80 GHz provide a tangible, if modest, advantage in latency-sensitive and lightly threaded workloads. The Xeon's higher core count cannot compensate for its lower 2.40 GHz base and 3.60 GHz boost clocks in these scenarios.

However, the Xeon's strength is not in winning benchmarks but in sustaining near-parity in multi-threaded tests despite a 14-core deficit. The Xeon E5-2699A v4 trails the Core i7-11700B by only 1.6% in Cinebench R15, R20, and R23 multi-core tests. This is a remarkable result for the Xeon, as it achieves this with 22 cores and 44 threads against the Core i7's 8 cores and 16 threads. The Xeon's 55 MB of shared L3 cache and quad-channel memory bandwidth of 76.8 GB/s likely help it keep its many cores fed, allowing it to nearly match a processor that has a significant per-core performance advantage. For workloads that scale perfectly across many threads, the Xeon is the more appropriate choice, as its 44 threads provide headroom that the Core i7 simply does not have, even if the measured multi-core scores are close.

Q: Do both processors support ECC memory?

A: No. The Intel Xeon E5-2699A v4 supports ECC memory, while the Intel Core i7-11700B does not have ECC memory support.

Q: Which processor has a higher transistor count?

A: The Intel Xeon E5-2699A v4 has a transistor count of 7,200 million, while the transistor count for the Intel Core i7-11700B is not specified in the data.

Head-to-Head Benchmarks

The head-to-head results are uniform, with the Core i7-11700B winning all six tests by a narrow margin. In Cinebench R15 multi-core, the Core i7 scores 1826 against the Xeon's 1796, a 1.6% difference. The single-core R15 test shows a similar story: 257 for the Core i7 versus 253 for the Xeon, also a 1.6% edge. Moving to Cinebench R20, the Core i7 posts 7609 in multi-core, beating the Xeon's 7486 by 1.6%, and in single-core, it scores 1074 against 1056, a 1.7% lead.

The largest absolute gap appears in the Cinebench R23 multi-core test, where the Core i7's 18119 score surpasses the Xeon's 17826 by 293 points, or 1.6%. The single-core R23 test sees the Core i7 at 2558 and the Xeon at 2516, a 42-point difference. The Geekbench multi-core test, which is only listed for the Xeon at 10118, does not have a corresponding head-to-head entry for the Core i7, but the Core i7's aggregate wins in all other categories suggest a consistent pattern. Notably, the Xeon's absolute multi-core scores are lower than the Core i7's in every Cinebench test, meaning the 22-core part cannot leverage its thread count to overcome the per-core deficit against the 8-core part in these specific workloads.

Specification Differences

The two processors differ fundamentally in almost every physical and platform specification. The Xeon E5-2699A v4 features 22 cores and 44 threads, while the Core i7-11700B has 8 cores and 16 threads. Clock speeds differ significantly: the Xeon has a base clock of 2.40 GHz and a boost clock of 3.60 GHz, whereas the Core i7 has a base clock of 3.20 GHz and a boost clock of 4.80 GHz. The Xeon has a TDP of 145 W, compared to the Core i7's much lower 65 W TDP.

The socket types are incompatible: the Xeon uses Intel Socket 2011-3, while the Core i7 uses Intel BGA 1787. The Xeon supports quad-channel memory with a bandwidth of 76.8 GB/s, while the Core i7 supports dual-channel memory with a bandwidth of 51.2 GB/s. ECC memory support is present on the Xeon but absent on the Core i7. The PCIe configuration also differs: the Xeon provides Gen 3 with 40 lanes, while the Core i7 provides Gen 4 with 20 lanes. The Core i7 includes integrated graphics (UHD Graphics Xe-LP), while the Xeon has none. Finally, the Xeon has a launch MSRP of $4938, while no launch MSRP is listed for the Core i7.

Architecture Differences

The architectural gap between these two parts spans four years and two distinct design philosophies. The Xeon E5-2699A v4 is built on Intel's 14 nm process node and uses the Broadwell-EP architecture, with a die size of 456 mm² and 7,200 million transistors. Its cache hierarchy includes 64 KB of L1 per core, 256 KB of L2 per core, and a large 55 MB shared L3 cache. The Core i7-11700B, in contrast, uses the Tiger Lake-H architecture on a 10 nm process node, with a die size of 190 mm² and no transistor count specified. Its cache configuration is per-core, with 80 KB of L1 and 1.25 MB of L2, but a smaller 24 MB shared L3 cache.

The Xeon's Broadwell-EP design targets server workloads requiring massive thread counts and large memory pools, as evidenced by its 44 threads and quad-channel memory controller. The Core i7's Tiger Lake-H design targets mobile platforms, emphasizing higher clock speeds and single-thread performance, along with a more modern 10 nm process and PCIe Gen 4 support. The Xeon's older 14 nm node and larger die are a product of its 2016 release, while the Core i7's 10 nm node and smaller die reflect its 2021 launch. The Core i7 also integrates a UHD Graphics (Xe-LP) GPU, a feature absent on the Xeon, which relies on discrete graphics. The Xeon's generation is listed as "Xeon E5 (Broadwell-EP)" and the Core i7's as "Core i7 (Tiger Lake-H)," highlighting their different market segments: Desktop for the Xeon and Mobile for the Core i7.
