CPU Comparison

FAQ

Q: Which processor has more cores and threads?

A: The Intel Core i7-975 has 4 cores and 8 threads, while the AMD Ryzen Embedded V1202B has 2 cores and 4 threads. Intel's part maintains a 2x advantage in both core count and thread count.

Q: How do the two CPUs compare in raw benchmark performance?

A: The AMD Ryzen Embedded V1202B wins all five head-to-head Cinebench tests, but by extremely narrow margins. In Cinebench R15 multicore, AMD scores 300 against Intel's 299, a delta of just 0.3%. The largest gap is in Cinebench R20 single-core, where AMD leads 176 to 175, or 0.6%.

Q: What are the power consumption differences?

A: The AMD Ryzen Embedded V1202B has a TDP of 15 watts, while the Intel Core i7-975 has a TDP of 130 watts. That is a substantial difference, Intel's chip draws over 8 times more power according to the TDP rating.

Q: Which processor supports faster memory bandwidth?

A: The Intel Core i7-975 uses triple-channel DDR3 with a memory bandwidth of 25.6 GB/s. The AMD Ryzen Embedded V1202B uses dual-channel DDR4, but its memory bandwidth figure is not listed in the data.

Q: Does either chip include integrated graphics?

A: Only the AMD Ryzen Embedded V1202B includes integrated graphics, specifically Radeon Vega 3. The Intel Core i7-975 has no integrated graphics at all.

Q: What is the production status of each processor?

A: The AMD Ryzen Embedded V1202B is listed as "Active" production, while the Intel Core i7-975 is "End-of-life." Intel's chip launched in 2009, while AMD's launched in 2018.

Architecture Differences

The architectural gap between these two processors is much larger than the benchmark scores suggest. The AMD Ryzen Embedded V1202B is built on the Zen architecture, codenamed "Great Horned Owl," using a 14 nm process node from GlobalFoundries. The Intel Core i7-975 uses the Nehalem architecture, codenamed Bloomfield, on Intel's 45 nm process. That is a three-generation process gap, and it shows in the transistor counts: AMD's chip packs 4,950 million transistors on a 210 mm² die, while Intel's older design uses just 731 million transistors on a larger 263 mm² die.

The cache configurations differ significantly. The AMD chip provides 128 KB of L1 cache per core and 512 KB of L2 cache per core, with 2 MB of shared L3 cache. Intel's part offers 64 KB of L1 per core and 256 KB of L2 per core, but compensates with a much larger 8 MB of shared L3 cache. This means Intel has 4x the L3 cache, which helps mitigate its older architecture's weaknesses in some workloads.

Memory support also diverges. The AMD processor uses dual-channel DDR4, while the Intel part uses triple-channel DDR3 with a rated bandwidth of 25.6 GB/s. Intel's memory bus is wider but uses older memory technology. The AMD chip has no PCIe generation listed in the data, while the Intel chip supports PCIe Gen 2.

The Intel Core i7-975 carries an unlocked multiplier, making it overclockable, whereas the AMD Ryzen Embedded V1202B is locked. The Intel part also includes the part number SLBEQ. The AMD chip integrates Radeon Vega 3 graphics, which the Intel chip lacks entirely.

The Verdict

The data tells a remarkably close story despite the massive architectural differences. The AMD Ryzen Embedded V1202B wins every single head-to-head benchmark, but by margins that are essentially within noise: 0.3% to 0.6% across Cinebench R15, R20, and R23 tests. Both processors sit at the 28th percentile of all CPUs, and their average benchmark scores are nearly identical, 1027 for AMD versus 1023 for Intel.

For a builder choosing between these two, the decision should come down to platform priorities rather than raw performance. The AMD part is the obvious choice for low-power or embedded applications: its 15-watt TDP, integrated Radeon Vega 3 graphics, active production status, and modern 14 nm process make it a functional, efficient option. The Intel Core i7-975, with its 130-watt TDP, no integrated graphics, and end-of-life status, is a relic from the high-end desktop era, one that requires a discrete GPU and substantial cooling.

However, the Intel chip does offer real advantages that the benchmarks do not capture. It has twice the cores and threads (4/8 versus 2/4), 4x the L3 cache (8 MB versus 2 MB), triple-channel memory support, and an unlocked multiplier for overclocking. The AMD chip's benchmark wins are so narrow that in real-world multithreaded workloads, the extra cores on the Intel side could plausibly overcome the small Cinebench deficit.

Pick the AMD Ryzen Embedded V1202B if you need a compact, low-power, actively produced processor with built-in graphics for an embedded or basic desktop system. Pick the Intel Core i7-975 if you have an existing Socket 1366 platform, need the extra cores and threads, or plan to overclock, though be prepared for its end-of-life status and high power draw.

Head-to-Head Benchmarks

The head-to-head results are striking in their consistency: the AMD Ryzen Embedded V1202B wins all five tests, but every margin is under 1%. In Cinebench R15 multicore, AMD scores 300 against Intel's 299, a 0.3% advantage. The Cinebench R20 multicore test shows the same pattern: 1253 versus 1249, again 0.3%. Single-core results are marginally more favorable to AMD, 176 versus 175 in R20 single-core (0.6%) and 421 versus 419 in R23 single-core (0.5%). The R23 multicore test rounds out the sweep with 2985 versus 2974, a 0.4% lead.

What makes these results remarkable is that the Intel Core i7-975 has 2x the cores and threads, a higher base clock (3.33 GHz versus 2.30 GHz), a higher boost clock (3.60 GHz versus 3.20 GHz), and 4x the L3 cache. The AMD chip's Zen architecture and modern 14 nm process are clearly doing substantial work to compensate for Intel's raw resource advantages. The 0.3-0.6% margins suggest that Cinebench workloads are not heavily core-bound at this performance level, or that the AMD architecture's efficiency gains are nearly perfectly offsetting Intel's core and cache advantages.

The average benchmark scores corroborate this: AMD sits at 1027, while Intel sits at 1023. Both processors have identical nearest-rival profiles in terms of score proximity, AMD's closest rival is the Intel Core i7-5650U at 1027 (0% delta), while Intel's closest rival is the AMD Ryzen 5 PRO 2500U at 1024 (0% delta). The data suggests these two chips are effectively performance peers in Cinebench, despite their radically different designs.

Where Each One Wins

The AMD Ryzen Embedded V1202B wins in every benchmark category recorded, but the practical interpretation depends on the broader context. Its wins are narrow but consistent, which suggests architectural efficiency rather than raw capability. The AMD chip is the clear winner in power-constrained scenarios: a 15-watt TDP versus 130 watts is not a small difference, and for embedded systems, fanless builds, or compact desktops, that efficiency advantage is decisive. The integrated Radeon Vega 3 graphics also give it a use-case win for basic display output without a discrete GPU. Its active production status and 2018 release date mean it is a current, supportable platform.

The Intel Core i7-975 wins in scenarios that require raw thread throughput, despite losing the Cinebench tests. With 4 cores and 8 threads versus 2 cores and 4 threads, the Intel part has structural advantages that Cinebench does not fully expose. Its 8 MB of L3 cache and triple-channel DDR3 memory (25.6 GB/s) provide bandwidth and caching headroom that could benefit memory-intensive workloads beyond the Cinebench suite. The unlocked multiplier makes it the only overclockable option of the two. The higher base and boost clocks (3.33 GHz and 3.60 GHz versus 2.30 GHz and 3.20 GHz) give it an advantage in lightly threaded tasks that are not captured by these particular benchmarks.

The launch MSRP of $1059 for the Intel part positions it at the high-end of its era, though its end-of-life status means that pricing context is historical. For a builder with an existing Socket 1366 motherboard, the Intel chip could still serve as a functional CPU, but the data shows the AMD Ryzen Embedded V1202B matches it in Cinebench while using a fraction of the power, making the AMD part the more rational choice for new builds.
