AMD Ryzen 9 PRO 7945 vs Intel Core i7-1185G7 Comparison

The Intel Core i7-1185G7 and AMD Ryzen 9 PRO 7945 occupy vastly different corners of the processor market, yet both sit at the 67th percentile of all CPUs in the database. That shared percentile masks a chasm in raw capability: the Ryzen 9 PRO 7945 wins all six head-to-head benchmark comparisons, with the Intel part trailing by roughly 78.8% in every single test. The data tells a story of two architectures designed for different workloads, where the mobile-focused Intel chip competes on efficiency and integration, while the AMD workstation part dominates through raw core count and modern process technology.

Where Each One Wins

The Intel Core i7-1185G7 does not win a single benchmark in the head-to-head comparison. The AMD Ryzen 9 PRO 7945 takes all six tests, leaving the Intel part with zero wins. However, the Intel chip’s strengths appear outside the direct comparison. Its benchmark suite includes PassMark tests where it posts respectable scores for a mobile processor: 104630 in data compression, 20126 in floating point math, and 34211 in integer math. These numbers, while far below the AMD part’s Cinebench results, indicate a capable performer for lightweight productivity tasks. The Intel chip also features Iris Xe-LP Graphics G7 with 96 execution units, which provides integrated graphics for everyday display output without a discrete GPU.

The AMD Ryzen 9 PRO 7945 wins decisively in every measurable compute benchmark. Its Cinebench R23 multi-core score of 39653 dwarfs the Intel chip’s 8416, representing a 78.8% advantage. Single-core performance tells a similar story: 5598 versus 1188 in Cinebench R23, again a 78.8% margin. This consistency across all six head-to-head tests—from Cinebench R15 through R23, both single and multi-core—suggests the AMD part’s advantage is architectural, not workload-specific. The Ryzen 9 PRO 7945 also supports ECC memory and DDR5, features absent from the Intel chip, making it suitable for data integrity-sensitive workstation tasks.

Architecture Differences

The two processors come from completely different design philosophies. Intel’s Core i7-1185G7 uses the Tiger Lake architecture, built on a 10 nm process at Intel’s own foundry. It employs Willow Cove cores with a die size of 144 mm². The AMD Ryzen 9 PRO 7945 uses Zen 4 architecture, manufactured on a 5 nm process by TSMC, with Raphael as the codename. AMD’s chip packs 13,140 million transistors across two chiplets, each 71 mm² in size.

Core configuration differs drastically. The Intel chip has 4 cores and 8 threads, while the AMD part offers 12 cores and 24 threads. Cache hierarchies also diverge: Intel provides 80 KB L1 per core, 1.25 MB L2 per core, and 12 MB shared L3. AMD provides 64 KB L1 per core, 1 MB L2 per core, and a massive 64 MB shared L3 cache. The AMD L3 cache is more than five times larger, which helps with data-heavy workloads. Memory support differs too—Intel uses DDR4 and LPDDR4X, while AMD only supports DDR5 with a memory bandwidth of 83.2 GB/s. Intel’s PCIe implementation offers Gen 4 with 4 lanes, whereas AMD provides Gen 5 with 24 lanes. The AMD chip also supports ECC memory, which the Intel part does not.

The socket and platform targets are entirely different. Intel uses BGA 1449, a soldered mobile socket, while AMD uses Socket AM5, a desktop and workstation platform. Intel’s integrated graphics are Iris Xe-LP with 96 EUs, while AMD includes Radeon Graphics. The AMD part is marked for Server/Workstation segment, while Intel’s is Mobile. Production status also differs: Intel’s chip is end-of-life, while AMD’s remains active.

Head-to-Head Benchmarks

The AMD Ryzen 9 PRO 7945 dominates every single benchmark in the head-to-head comparison. In Cinebench R15 multi-core, AMD scores 3996 against Intel’s 848, a delta of -78.8% for the Intel chip. Single-core R15 shows AMD at 564 versus Intel at 119, again -78.8%. Moving to Cinebench R20, AMD posts 16654 multi-core and 2351 single-core, while Intel manages 3534 and 498 respectively, with the same -78.8% gap. Cinebench R23 continues the pattern: AMD reaches 39653 multi-core and 5598 single-core, while Intel trails at 8416 and 1188. Every test shows an identical -78.8% delta, indicating the performance ratio is remarkably consistent across different Cinebench versions and workload types.

This consistency suggests the AMD part’s advantage comes from fundamental architectural superiority rather than optimization for specific tests. The 12-core, 24-thread configuration with 64 MB L3 cache and 5.4 GHz boost clock simply outperforms the 4-core, 8-thread Intel chip with 12 MB L3 and 4.8 GHz boost. The AMD chip’s 5 nm process from TSMC also provides a transistor density advantage over Intel’s 10 nm node. The data shows no single benchmark where the Intel chip comes close to closing the gap—the smallest absolute difference is in Cinebench R15 single-core, where AMD’s 564 still outpaces Intel’s 119 by a factor of nearly five.

The Verdict

The data clearly indicates that the AMD Ryzen 9 PRO 7945 is the superior processor in every direct benchmark comparison. Anyone needing maximum multi-threaded performance for workstation or server tasks should choose the AMD part, given its 12 cores, 24 threads, 64 MB L3 cache, and 5.40 GHz boost clock. The AMD chip’s ECC memory support and DDR5 compatibility further reinforce its workstation positioning. The Intel Core i7-1185G7, with its 28-watt TDP and mobile socket, is designed for laptops and portable devices, not for competing with desktop-class processors. Its integrated Iris Xe graphics and lower power draw make it suitable for mobile productivity, but its end-of-life status and 4-core limitation mean it cannot match the AMD part in compute-heavy workloads.

However, the Intel chip’s benchmark scores in PassMark tests—104630 in data compression, 20126 in floating point math—show it handles everyday tasks adequately. For users on a mobile platform who need a capable processor for office work, web browsing, and light content creation, the Intel chip remains viable, though its 67th percentile ranking and zero head-to-head wins suggest it is outclassed by the AMD part. The AMD Ryzen 9 PRO 7945, despite also sitting at the 67th percentile, achieves that ranking with far higher absolute scores across a smaller benchmark suite. The verdict from the data is unambiguous: the AMD part wins every benchmark, offers more cores, faster clocks, larger cache, and newer memory support. Choose AMD for performance, choose Intel only if the mobile form factor or integrated graphics are absolute requirements.
