CPU Comparison

The Intel Core i3-10300 and the AMD Opteron 6348 occupy vastly different positions in the market, yet their benchmark results place them in a near-dead heat. The data shows the Core i3-10300 edges out the Opteron in every single Cinebench test, though the largest margin is a scant 1.1%. The Opteron, a server-class part with triple the physical cores, is effectively matched by a desktop quad-core from eight years later. The average benchmark scores are almost identical: 1934 for the Intel part versus 1930 for the AMD part, a difference of 0.2%. Both processors sit at the 43rd percentile of all CPUs, indicating they are middle-of-the-pack performers in the current landscape.

FAQ

Q: Which processor has a higher average benchmark score?

Q: Which processor supports ECC memory?

A: The AMD Opteron 6348 supports ECC memory, while the Intel Core i3-10300 does not. This reflects the Opteron's server-oriented design, which requires error correction for reliability in data-center workloads.

Q: What are the memory bandwidth capabilities of each chip?

A: The AMD Opteron 6348 features a quad-channel DDR3 memory bus with a bandwidth of 59.7 GB/s. The Intel Core i3-10300 uses a dual-channel DDR4 bus, delivering a lower peak bandwidth of 42.7 GB/s.

Q: What is the release date and production status of each processor?

A: The AMD Opteron 6348 was released on November 4, 2012, and is marked as end-of-life. The Intel Core i3-10300 was released on April 29, 2020, and is still listed as active in production.

Architecture Differences

The architectural chasm between these two processors is immense, reflecting their distinct design goals and eras. The Intel Core i3-10300 is built on the Comet Lake architecture using a 14 nm process node from Intel. It features 4 cores and 8 threads, a configuration that leverages Hyper-Threading to double the logical processing units. The AMD Opteron 6348, codenamed Abu Dhabi, uses the Piledriver architecture on a 32 nm process from GlobalFoundries. It packs 12 physical cores but only 12 threads, meaning it lacks simultaneous multithreading; each core is a single thread. The Opteron’s transistor count is listed at 2,400 million, spread across a dual-die design with a total die size of 2x 315 mm², whereas the Intel chip does not disclose these figures in the data.

Cache hierarchies also differ fundamentally. The Intel Core i3-10300 has 64 KB of L1 cache per core and 256 KB of L2 per core, with a shared 8 MB L3 pool. The AMD Opteron 6348 has a total of 576 KB L1 cache and 2 MB of L2 per module, with 8 MB of L3 per die. The Opteron’s cache layout is module-based, a hallmark of the Piledriver design that shares resources between pairs of cores. Memory support diverges as well: the Intel chip uses dual-channel DDR4, while the AMD part uses quad-channel DDR3. PCIe connectivity also differs, with the Intel offering Gen 3 with 16 lanes from the CPU, and the AMD limited to Gen 2.

The Intel processor includes integrated UHD Graphics 630, a feature absent on the Opteron, which has no integrated graphics. The market segments are polar opposites: the Core i3-10300 is a desktop part, while the Opteron 6348 targets server and workstation platforms. The manufacturing timeline also separates them, with the Opteron released in 2012 and the Intel chip in 2020.

Head-to-Head Benchmarks

The benchmark data presents a fascinating case of statistical parity. The Intel Core i3-10300 wins all six head-to-head comparisons, but the margins are consistently under 1.1%. In Cinebench R15 multi-core, the Intel scores 673 against the AMD's 672, a 0.1% difference. The single-core R15 test shows a slightly larger gap, with Intel at 95 and AMD at 94, a 1.1% lead. Moving to Cinebench R20, the multi-core scores are 2808 for Intel and 2802 for AMD, a 0.2% delta; single-core results are 396 vs 395, a 0.3% lead. The most modern test, Cinebench R23, shows Intel ahead by 0.2% in both multi-core (6687 vs 6672) and single-core (944 vs 942) workloads.

The practical interpretation is that these two processors deliver nearly identical rendering performance in the Cinebench suite. The Opteron’s 12 cores do not translate into a multi-core advantage because each of its cores is significantly slower and it lacks SMT. The Intel i3-10300, with only 4 cores but 8 threads, manages to match the Opteron’s throughput. The single-core results are particularly telling: despite a 0.90 GHz higher base clock and a 1.00 GHz higher boost clock, the Intel chip only leads by 1.1% at most, indicating the per-clock performance of the older Piledriver architecture is not as far behind as one might expect, though it is still behind.

Specification Differences

The specification sheets reveal stark contrasts across nearly every category. The Intel Core i3-10300 has 4 cores and 8 threads, while the AMD Opteron 6348 has 12 cores and 12 threads. The Intel chip runs at a base clock of 3.70 GHz and boosts to 4.40 GHz; the Opteron operates at 2.80 GHz base and 3.40 GHz boost. Thermal design power differs significantly: the Intel part is rated at 62 watts, the AMD at 115 watts. The sockets are incompatible: Intel Socket 1200 for the i3-10300, AMD Socket G34 for the Opteron. The process nodes are 14 nm (Intel) versus 32 nm (GlobalFoundries).

Memory support splits on generation and channel count: Intel uses DDR4 in dual-channel mode, while AMD uses DDR3 in quad-channel mode. The memory bandwidth is higher on the AMD part at 59.7 GB/s versus 42.7 GB/s for Intel. ECC memory is supported only on the Opteron. PCIe capability differs, with Intel providing Gen 3 and 16 lanes, while AMD only lists Gen 2 without a lane count. The Intel chip has integrated UHD Graphics 630; the AMD chip has none. The market segment is Desktop for Intel and Server/Workstation for AMD. Production status is Active for Intel and End-of-life for AMD. The release dates are 2020-04-29 for Intel and 2012-11-04 for AMD. The Opteron has a launch MSRP of $575, while no MSRP is listed for the Intel part. The Opteron also lists 2,400 million transistors and a 2x 315 mm² die size, figures not provided for the Intel chip.

Where Each One Wins

Based strictly on the benchmark wins, the Intel Core i3-10300 is the outright victor, taking all six Cinebench tests. Its wins are most pronounced in single-core performance, where it leads by up to 1.1% in Cinebench R15. This makes the Intel part the better choice for workloads that rely on single-threaded responsiveness, such as general desktop applications, legacy software, and lightly-threaded games. The data also shows it achieves this with a lower TDP of 62 watts, indicating higher power efficiency for the performance delivered. The Intel chip also wins on platform modernity, offering PCIe Gen 3 and DDR4 memory support, which are relevant for newer system components.

The AMD Opteron 6348, while losing every benchmark, has strengths that the data supports in non-benchmark areas. It supports ECC memory, a critical feature for data integrity in server environments. It offers quad-channel memory with a higher bandwidth of 59.7 GB/s, which could benefit memory-intensive server workloads that the Cinebench suite does not measure. Its 12 physical cores, while not helping in these specific tests, could theoretically provide more parallel throughput in highly optimized multi-threaded server applications, though the data does not show this benefit in the available benchmarks. The Opteron is also a server-class part with a launch MSRP of $575, positioning it in a different market segment entirely.

The practical verdict from the data is clear: for the benchmarks tested, the Intel Core i3-10300 is the better performer, though the margins are so thin that real-world differences would be imperceptible. The Opteron’s advantages lie in platform features like ECC and memory bandwidth, not raw computational speed as measured by Cinebench. The i3-10300’s win count of 6 to 0 is decisive, but the largest delta of 1.1% underscores that this is a battle of near-equals in the tested workloads.
