AMD Opteron 6348 vs Intel Core i7-1180G7 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual scenario: the Intel Core i7-1180G7 and AMD Opteron 6348 produce identical scores across every benchmark test in the database. In Cinebench R15 multicore, both processors score 672. In the single-core variant of the same test, both achieve 94. Moving to Cinebench R20, the multicore result for each is 2802, while the single-core result is 395. Cinebench R23 shows a multicore score of 6672 and a single-core score of 942 for both parts. The head-to-head table lists six wins for the Intel processor and zero for the AMD part, though every margin is zero percent. This means the delta between them is exactly nil in all recorded workloads.

The average benchmark score for both processors is 1930. This places them in the same percentile among all CPUs, at the 43rd percentile. The nearest rivals in the database further contextualize this performance tier. The Intel Core i3-10300 sits just above with an average score of 1934, which represents a 0.2 percent advantage over both processors in question. The Intel Xeon E3-1231 v3 trails slightly with a score of 1925, a 0.3 percent deficit. The Intel Core i3-10305T follows at 1922, a 0.4 percent gap. These differences are small enough that they fall within typical run-to-run variation for benchmark software, but the database records them as precise figures.

Interpreting the scores requires recognizing that the two chips achieve parity despite radically different designs. The Opteron 6348 is a 12-core, 12-thread server processor with a base clock of 2.80 GHz and a boost clock of 3.40 GHz. The Core i7-1180G7 is a 4-core, 8-thread mobile processor with a base clock of 1.30 GHz and a boost clock of 4.60 GHz. The fact that these two configurations produce identical Cinebench results suggests that the Intel part's higher boost clock and newer architecture compensate for its lower core count in these specific workloads. The Cinebench suite, which scales with both single-thread efficiency and multi-thread throughput, evidently lands both chips at the same performance point.

The single-core results are particularly telling. The Opteron's 12 cores do nothing to help it in Cinebench R23 single-core, where it scores 942. The Core i7-1180G7 matches that score exactly. Since the Intel chip runs four cores with hyper-threading, its single-core performance is likely driven by its 4.60 GHz boost capability. The AMD chip's 3.40 GHz boost is lower, but the Piledriver architecture from 2012 apparently delivers comparable single-thread performance in this test. The result is a perfect tie, which is rare in processor comparisons.

For multi-core workloads, the Opteron's 12 physical cores should theoretically give it a substantial advantage over the Intel's four cores and eight threads. Yet Cinebench R23 multicore shows both at 6672. This could indicate that the Intel processor's thermal and power management allows it to sustain high clocks across its cores for the duration of the test, while the Opteron, despite having more cores, does not scale as efficiently in this benchmark. The database does not provide per-core clock behavior during testing, but the final scores are unambiguous.

In Cinebench R15 and R20, the same pattern holds. The multicore scores of 672 and 2802 respectively are identical for both processors. The single-core scores of 94 and 395 are also identical. No workload in the database separates these two chips by even one point. This is a statistical oddity, but the database records it as fact.

The nearest rival data reinforces that both processors occupy a specific performance tier. Being at the 43rd percentile means they outperform a majority of the CPUs in the database but lag behind the upper half. The Core i3-10300, a mainstream desktop part, edges them out by a negligible margin. The Xeon E3-1231 v3, an older server chip, is nearly equal. This suggests that the Core i7-1180G7 and Opteron 6348 deliver comparable compute throughput to mid-range desktop and entry-level server parts from their respective eras.

Architecture Differences

The Intel Core i7-1180G7 is built on Intel's 10 nm process node, fabricated in-house by Intel. It belongs to the Tiger Lake family, with the codename Tiger Lake-U. The architecture is Willow Cove-U, part of the Core i7 generation. The processor has four cores and eight threads, with a base clock of 1.30 GHz and a boost clock of 4.60 GHz. Its thermal design power is 9 watts, which places it firmly in the ultra-low-power mobile segment. The die size is 144 mm². Cache is organized as 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3.

The AMD Opteron 6348 is built on a 32 nm process node, fabricated by GlobalFoundries. It belongs to the Opteron 6000 series, with the codename Abu Dhabi and the Piledriver architecture. The generation is labeled Opteron (Abu Dhabi). This processor has 12 cores and 12 threads, indicating no simultaneous multi-threading. Its base clock is 2.80 GHz, and its boost clock is 3.40 GHz. The thermal design power is 115 watts, a server-class power envelope. The die is composed of two 315 mm² dies, totaling 2,400 million transistors. Cache consists of 576 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die.

The process node difference is stark: 10 nm versus 32 nm. The Intel chip packs its four cores into a much smaller die, while the AMD chip uses two large dies to accommodate 12 cores. Transistor count for the Intel part is not recorded in the database, but the AMD part's 2,400 million transistors reflects a much older manufacturing process. The Intel part's 10 nm process allows for higher clock speeds at dramatically lower power, which explains the 9-watt TDP against the Opteron's 115-watt TDP.

Memory support differs substantially. The Intel Core i7-1180G7 supports LPDDR4X memory on a dual-channel bus, with a memory bandwidth of 34.1 GB/s. It does not support ECC memory. The AMD Opteron 6348 supports DDR3 memory on a quad-channel bus, with a memory bandwidth of 59.7 GB/s. It does support ECC memory. The Opteron's higher raw bandwidth is typical for a server part, though the Intel chip's LPDDR4X support is designed for low-power mobile operation.

PCI Express support also differs. The Intel processor provides Gen 4 with four lanes from the CPU only. The AMD processor provides Gen 2, with no lane count specified in the database. This reflects the generational gap: Gen 4 PCIe offers substantially higher bandwidth per lane than Gen 2, which was current when the Opteron launched.

Integrated graphics are present only on the Intel part. The Core i7-1180G7 includes Iris Xe-LP Graphics G7 with 96 execution units. The Opteron 6348 has no integrated graphics, which is standard for server processors that rely on discrete graphics or remote management.

The memory bus width and ECC support point to different intended workloads. The Opteron's quad-channel DDR3 with ECC is designed for reliability and throughput in server environments. The Intel part's dual-channel LPDDR4X without ECC is optimized for battery life and space constraints in mobile devices.

Production status for both is end-of-life. The Opteron 6348 was released on 2012-11-04, while the Core i7-1180G7 was released on 2021-03-30. The nearly nine-year gap between releases explains many of the architectural differences, yet the benchmark scores remain identical.

The Verdict

The data shows that the Intel Core i7-1180G7 and AMD Opteron 6348 deliver identical performance across all recorded Cinebench workloads. The six head-to-head tests all result in zero percent deltas, and the average benchmark score is the same at 1930. No workload in the database favors one processor over the other.

For mobile users, the Core i7-1180G7 is the obvious choice based on the recorded specifications. Its 9-watt TDP makes it suitable for fanless or low-power designs, while its 4.60 GHz boost clock provides responsiveness in single-threaded tasks. Its integrated Iris Xe-LP Graphics G7 with 96 execution units adds GPU capability that the Opteron entirely lacks. The LPDDR4X memory support and Gen 4 PCIe further align with modern mobile platforms.

For server or workstation environments, the Opteron 6348 offers advantages that are not reflected in the Cinebench scores. Its 12 physical cores provide parallel throughput potential, and its ECC memory support is critical for data integrity in long-running server workloads. The quad-channel DDR3 with 59.7 GB/s bandwidth exceeds the Intel part's 34.1 GB/s. The 115-watt TDP, while high, is typical for a socket G34 server processor designed for multi-socket configurations.

The benchmark parity suggests that for raw Cinebench throughput, neither chip has an edge. The selection between them should rest on platform requirements rather than performance scores. The Core i7-1180G7 is a complete mobile solution with graphics and low power draw. The Opteron 6348 is a server workhorse with ECC and high memory bandwidth. Both are end-of-life, so availability may be limited.

The 43rd percentile ranking for both indicates they are mid-pack performers in the database. The nearest rivals, the Core i3-10300 and Xeon E3-1231 v3, are all within 0.4 percent of each other, forming a tight cluster of similar-performing CPUs. The Opteron and Core i7 sit squarely in that cluster.

Users requiring a compact, low-power system with integrated graphics should choose the Intel part. Users building a server with ECC memory and high memory throughput should choose the AMD part. Neither choice sacrifices benchmark performance, as the recorded scores are identical.
