Intel Core i7-5775R vs Intel Xeon D-1712TR Comparison

Where Each One Wins

The recorded benchmark data presents a remarkably one-sided picture. Across every Cinebench iteration in the database, the Intel Xeon D-1712TR claims victory. The Core i7-5775R does not register a single win in the head-to-head comparison. This is not a case of one chip dominating in certain workloads while ceding others; the Xeon D-1712TR is consistently ahead in both single-core and multi-core tests.

What makes this interesting is the nature of the two processors. The Core i7-5775R targets desktop users, while the Xeon D-1712TR is built for server and workstation environments. Yet the data does not show the desktop part clawing back ground in lightly threaded tasks. In Cinebench R15 single-core, the Xeon leads 98 to 90. In R20 single-core, it leads 410 to 376. The pattern holds in multi-core as well: R15 shows 698 versus 641, R20 shows 2911 versus 2671, and R23 shows 6931 versus 6360.

The margin is remarkably consistent, hovering around 8.2% to 8.3% in favor of the Xeon across all six tests. This uniformity suggests a fundamental architectural advantage rather than workload-specific optimization. The Xeon does not merely win, it wins by nearly the same proportion everywhere. For users prioritizing raw Cinebench throughput, the Xeon D-1712TR is the clear choice based purely on the numbers.

Architecture Differences

The two processors come from different eras and different design philosophies. The Core i7-5775R is built on Broadwell, a 14 nm architecture that Intel released in 2015. It uses the Intel BGA 1364 socket and belongs to the desktop market segment. The Xeon D-1712TR, by contrast, is an Ice Lake-D part on a 10 nm process, released in 2022, using the Intel BGA 2227 socket and aimed at server and workstation deployments.

The cache hierarchies reveal significant divergence. The Core i7-5775R offers 64 KB of L1 cache per core, 256 KB of L2 per core, and 6 MB of shared L3. The Xeon D-1712TR provides 80 KB of L1 per core, a substantially larger 1.25 MB of L2 per core, and 10 MB of shared L3. The Xeon's larger caches, especially the L2, likely contribute to its consistent benchmark advantage.

Memory support also differs sharply. The Core i7-5775R uses DDR3 with dual-channel memory and a bandwidth of 29.9 GB/s. The Xeon D-1712TR uses DDR4 with triple-channel memory and a bandwidth of 57.6 GB/s, nearly double. The Xeon also supports ECC memory, while the Core i7 does not. PCIe capabilities differ as well: the Core i7 offers Gen 3 with 16 lanes, while the Xeon provides Gen 4 with 16 lanes.

The integrated graphics situation is a notable differentiator. The Core i7-5775R includes Iris Pro Graphics 6200, while the Xeon D-1712TR has no integrated graphics at all. This makes sense given their target markets: a desktop processor often needs display output, while a server processor typically relies on a discrete GPU or none at all. The Xeon's TDP is lower at 40 watts versus 65 watts, reflecting its efficiency-oriented server design.

Specification Differences

The two processors diverge on nearly every major specification. The Core i7-5775R uses the Broadwell architecture on a 14 nm process, while the Xeon D-1712TR uses Ice Lake on a 10 nm process. The Core i7 has a base clock of 3.30 GHz and boost of 3.80 GHz; the Xeon has a base clock of 2000.00 MHz and boost of 3.10 GHz. TDP differs significantly: 65 watts for the Core i7 versus 40 watts for the Xeon.

Socket compatibility is distinct: Intel BGA 1364 for the Core i7, Intel BGA 2227 for the Xeon. Cache configurations differ at every level: L1 is 64 KB per core versus 80 KB per core, L2 is 256 KB per core versus 1.25 MB per core, and L3 is 6 MB shared versus 10 MB shared. Memory support shows DDR3 dual-channel for the Core i7 and DDR4 triple-channel for the Xeon, with bandwidths of 29.9 GB/s and 57.6 GB/s respectively.

ECC memory support is absent on the Core i7 and present on the Xeon. PCIe generation differs: Gen 3 for the Core i7, Gen 4 for the Xeon, both with 16 lanes. The Core i7 includes Iris Pro Graphics 6200; the Xeon has none. Market segments differ: desktop for the Core i7, server/workstation for the Xeon. Release dates are far apart: May 2015 for the Core i7, February 2022 for the Xeon. Production status shows end-of-life for the Core i7 and active for the Xeon. The launch MSRP for the Core i7-5775R is $384, and for the Xeon D-1712TR it is $263.

Head-to-Head Benchmarks

The head-to-head data is striking in its consistency. The Xeon D-1712TR wins all six recorded benchmark comparisons. In Cinebench R15 multi-core, the Xeon scores 698 against the Core i7's 641, a delta of negative 8.2% from the Core i7's perspective. The single-core R15 test shows the same margin: 98 versus 90, again an 8.2% deficit for the Core i7.

Cinebench R20 continues the trend. Multi-core results show the Xeon at 2911 and the Core i7 at 2671, an 8.2% gap. Single-core R20 shows 410 versus 376, an 8.3% deficit. The pattern repeats in R23: multi-core scores of 6931 for the Xeon and 6360 for the Core i7 represent an 8.2% difference, while single-core scores of 978 versus 897 represent an 8.3% difference.

The near-identical delta percentages across every test suggest that the Xeon's advantage is systemic. It is not that the Xeon excels in one type of workload; it is uniformly faster across the entire Cinebench suite. The Core i7's higher clock speeds, 3.80 GHz boost versus 3.10 GHz, do not translate into benchmark wins. The Xeon's architectural advantages, including larger caches, newer process node, and faster memory, appear to overcome the clock speed deficit.

The average benchmark score in the database tells a similar story, though with a narrower margin. The Core i7-5775R has an average score of 2031, while the Xeon D-1712TR has an average of 2004. However, this average includes Geekbench scores for the Core i7, which the Xeon does not have recorded. The Core i7's Geekbench multi-core score is 3996 and single-core is 1218. The Xeon has no Geekbench entries in the database, so its average is based solely on Cinebench results.

Both processors sit at the 45th percentile among all CPUs in the database. The Core i7's nearest rivals include the Intel Xeon E3-1240 v5 with a delta of 0%, the Xeon E3-1280 v5 and E3-1260L v5 at 0.1%, and the Xeon E-2124G at negative 0.1%. The Xeon D-1712TR's nearest rivals are the Intel Core i5-8400H at 0%, the Core i5-8300H at negative 0.1%, the AMD Ryzen 7 2800H at 0.1%, and the Core i5-8400T at 0.1%. These rival comparisons place both processors in similar overall performance tiers, despite the Xeon's clear head-to-head advantage in Cinebench.

The Verdict

The data points to a straightforward conclusion: the Intel Xeon D-1712TR is the faster processor in every recorded benchmark. It wins all six Cinebench tests with a consistent margin of roughly 8.2% to 8.3%. For users whose workloads resemble Cinebench rendering tasks, the Xeon D-1712TR is the superior choice.

The Core i7-5775R does have one major advantage: integrated graphics. It includes Iris Pro Graphics 6200, while the Xeon has none. A system builder who needs a display output without a discrete GPU would have to consider the Core i7 for that reason alone. The Core i7 also has higher clock speeds, which might benefit certain legacy workloads not represented in the database, but the recorded benchmarks do not support that expectation.

The Xeon D-1712TR offers additional server-oriented features that the Core i7 lacks: ECC memory support, triple-channel DDR4 with higher bandwidth, PCIe Gen 4, and a lower TDP of 40 watts versus 65 watts. Its active production status and newer 10 nm architecture suggest better long-term availability and efficiency. The Core i7 is end-of-life, which may matter for procurement decisions.

For server or workstation deployments where ECC memory and reliability are priorities, the Xeon D-1712TR is the clear pick. For desktop users who require integrated graphics and can accept lower benchmark scores, the Core i7-5775R remains functional but is objectively slower in Cinebench. The data does not show any workload category where the Core i7 wins, so the verdict rests on features rather than performance. The Xeon D-1712TR is the benchmark champion; the Core i7-5775R is the legacy desktop option with graphics capability.
