Intel Core i5-10210Y vs Intel Core i7-975 Comparison

# Head-to-Head Benchmarks

The benchmark data records a decisive sweep for the Intel Core i5-10210Y across every Cinebench test in the comparison. The i5-10210Y wins all five recorded head-to-head benchmarks, while the Intel Core i7-975 does not secure a single victory. This is not a close contest by any measure; the margins are consistent and significant.

Starting with multi-core performance, the i5-10210Y outscores the i7-975 in Cinebench R15 multicore, posting 350 points against 299 points. That is a delta of -14.6 percent from the perspective of the i7-975, meaning the i5-10210Y is roughly 15 percent faster in this workload. The pattern holds in Cinebench R20 multicore, where the i5-10210Y records 1461 points versus 1249 points for the i7-975, a delta of -14.5 percent. In the newer Cinebench R23 multicore test, the i5-10210Y again leads with 3479 points compared to 2974 points, maintaining that same -14.5 percent gap.

Single-core results show an even slightly larger relative advantage. In Cinebench R20 single-core, the i5-10210Y scores 206 points while the i7-975 manages 175 points, a delta of -15 percent. The Cinebench R23 single-core test follows the same trajectory: the i5-10210Y reaches 491 points versus 419 points for the i7-975, a delta of -14.7 percent. Interestingly, the i7-975 has no recorded single-core score for Cinebench R15 in the database, while the i5-10210Y posts 51 points there; this missing data point does not affect the overall sweep.

The average benchmark scores reflect this consistent superiority. The i7-975 has an average benchmark score of 1023, and the i5-10210Y sits at 1006. Despite the i5-10210Y having a slightly lower average, the head-to-head Cinebench tests all favor the newer chip. The percentiles tell a similar story: the i7-975 sits at the 28th percentile among all CPUs, and the i5-10210Y is at the 27th percentile. These are nearly identical overall standings, yet the direct comparison reveals a clear edge for the i5-10210Y in every measured workload.

The nearest rivals for each part provide additional context. The i7-975 is bracketed by the AMD Ryzen 5 PRO 2500U at an average score of 1024 with a delta of 0 percent, the AMD Phenom II X6 1075T at 1024 with a delta of -0.1 percent, the Intel Pentium Gold G5600 at 1022 with a delta of 0.1 percent, and the Intel Processor N150 at 1025 with a delta of -0.2 percent. The i5-10210Y, by contrast, is nearest to the Intel Core i7-880 at 1006 with a delta of 0 percent, the AMD FX-9830P at 1006 with a delta of 0 percent, the Intel Core i7-2630QM at 1005 with a delta of 0.1 percent, and the Intel Processor N100 at 1007 with a delta of -0.1 percent. Both chips are average performers in their respective peer groups, but the i5-10210Y is consistently the stronger part when measured head-to-head.

# Where Each One Wins

The data is unambiguous: the Intel Core i5-10210Y wins every benchmark category that has a direct comparison. There is no workload in the recorded dataset where the Intel Core i7-975 comes out ahead. This means the i5-10210Y is the better choice for both multi-threaded and single-threaded applications, as evidenced by its wins across Cinebench R15, R20, and R23 for multi-core, and R20 and R23 for single-core.

For users focused on modern rendering tasks, the i5-10210Y is the clear pick. Its Cinebench R23 multicore score of 3479 represents a 14.5 percent improvement over the i7-975's 2974. Similarly, for single-threaded responsiveness, the i5-10210Y's R23 single-core score of 491 is 14.7 percent higher than the i7-975's 419. These are not marginal differences; they translate to noticeable gains in applications that rely heavily on CPU throughput.

The i7-975 does have some qualitative advantages that the benchmark scores do not capture. It is a desktop part with a 130 watt TDP, while the i5-10210Y is a mobile part with a 9 watt TDP. This suggests the i7-975 may be intended for sustained heavy workloads in a desktop chassis, whereas the i5-10210Y is designed for battery-powered devices. However, in pure performance measurements, the i5-10210Y outperforms the i7-975 in every recorded test, which is remarkable given the i7-975's much higher power envelope.

The i7-975 also has an unlocked multiplier, allowing overclocking, while the i5-10210Y does not. This could theoretically allow the i7-975 to close the gap in hands-on scenarios, but the recorded benchmark data shows no such advantage at stock settings. For users who do not overclock, the i5-10210Y is simply the faster processor in all measured metrics.

# Architecture Differences

The two processors come from very different eras and design philosophies. The Intel Core i7-975 is based on the Nehalem architecture, specifically the Bloomfield codename, built on a 45 nm process node at Intel's foundry. It integrates 731 million transistors on a 263 mm² die. The Intel Core i5-10210Y uses the Comet Lake architecture, codenamed Comet Lake-Y, built on a 14 nm process node, also at Intel. The database does not record transistor count or die size for the i5-10210Y.

Both processors have 4 cores and 8 threads, so the thread count is identical. The cache hierarchy differs slightly. The i7-975 has 64 KB of L1 cache per core and 256 KB of L2 cache per core, matching the i5-10210Y. The difference appears in L3 cache: the i7-975 has 8 MB shared L3, while the i5-10210Y has 6 MB shared L3. This gives the i7-975 a 2 MB L3 advantage, yet it still loses in every benchmark, suggesting that other architectural factors dominate.

Clock speeds tell a different story. The i7-975 has a base clock of 3.33 GHz and a boost clock of 3.60 GHz. The i5-10210Y has a base clock of 1000 MHz, which is 1.00 GHz, and a boost clock of 4.00 GHz. The i5-10210Y's much higher boost clock, combined with a significantly lower base clock, indicates an aggressive turbo behavior that allows it to reach higher performance on demand while maintaining low idle power. The i7-975's clocks are more modest and flat by comparison.

The memory support also differs. The i7-975 supports DDR3 with a triple-channel memory bus and a memory bandwidth of 25.6 GB/s. The i5-10210Y also supports DDR3, but the database does not record a memory bus width or memory bandwidth figure. The i5-10210Y does include integrated UHD Graphics, while the i7-975 has no integrated graphics recorded. This makes the i5-10210Y a more complete package for systems without a discrete GPU.

The i7-975 uses Intel Socket 1366, while the i5-10210Y uses Intel BGA 1440. The i7-975 is a desktop part with a 130 watt TDP, and the i5-10210Y is a mobile part with a 9 watt TDP. The i7-975 has an unlocked multiplier, whereas the i5-10210Y does not. The i7-975 supports PCIe Gen 2, while the i5-10210Y has no PCIe version recorded. The production statuses also differ: the i7-975 is end-of-life, while the i5-10210Y is active.

# The Verdict

The recorded data points to a single conclusion: the Intel Core i5-10210Y is the faster processor in every measured benchmark. Its wins across Cinebench R15, R20, and R23, for both multi-core and single-core tests, are consistent and substantial, with deltas ranging from -14.5 percent to -15 percent relative to the i7-975. Anyone comparing these two parts for performance should choose the i5-10210Y without hesitation.

The i7-975 does retain certain advantages that are not reflected in the benchmark scores. It has a larger L3 cache at 8 MB versus 6 MB, a triple-channel memory bus with 25.6 GB/s bandwidth, and an unlocked multiplier for overclocking. It also supports PCIe Gen 2. These features may appeal to users with specific legacy requirements or those planning to overclock, but the stock performance data shows no benefit.

The i5-10210Y, on the other hand, offers a much lower TDP of 9 watts versus 130 watts, making it far more suitable for mobile and power-constrained environments. It also includes integrated UHD Graphics, eliminating the need for a separate GPU in basic systems. Its active production status and newer architecture (14 nm Comet Lake versus 45 nm Nehalem) mean it is a more modern and sustainable choice.

For users building a new system or upgrading from an older platform, the i5-10210Y is the clear winner based on benchmark results. For users with a specific need for the i7-975's desktop socket, memory bandwidth, or overclocking capability, the i7-975 may still be relevant, but it will be slower in all recorded Cinebench tests. The data is unambiguous: the i5-10210Y outperforms the i7-975 across the board.
