The Verdict

The data in the database separates these two processors into entirely different performance classes. The Intel Core 9 273PQE sits at the 93rd percentile among all CPUs, with an average benchmark score of 66099. The Intel Processor 300T sits at the 50th percentile, with no recorded benchmark scores in the database. For workloads that rely on multi-threaded throughput, the Core 9 273PQE delivers 12 cores and 24 threads versus 2 cores and 4 threads for the Processor 300T. The Cinebench R23 multicore score of 39190 for the Core 9 indicates a processor built for heavy parallel workloads. The Processor 300T, with its 2-core configuration, is positioned for basic computing tasks. The Core 9 also carries a much larger 36 MB L3 cache, which supports demanding applications that benefit from large working sets. The Processor 300T's 6 MB L3 cache is suited for lighter workloads. The 125 watt TDP of the Core 9 versus the 35 watt TDP of the Processor 300T further confirms the Core 9 is designed for sustained high-performance operation, while the Processor 300T is designed for low-power environments. The Core 9 also includes ECC memory support, a feature absent on the Processor 300T, which matters for data-integrity-sensitive environments. The Processor 300T has a smaller die size of 163 mm², but no die size is recorded for the Core 9, so no direct comparison can be made on that metric. The Core 9 is the clear choice for users who need maximum processing capability, while the Processor 300T fits scenarios where modest performance and low power draw are the priorities.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so no direct side-by-side test scores exist between the Intel Core 9 273PQE and the Intel Processor 300T. However, the Intel Core 9 273PQE has a full set of recorded benchmark scores, which gives a clear picture of its capabilities. The Cinebench R23 multicore score of 39190 and single-core score of 5532 show a processor with strong performance in both parallel and single-threaded tasks. The Cinebench R20 multicore score of 16459 and single-core score of 2323 follow the same pattern. The Cinebench R15 multicore score of 3950 and single-core score of 557 round out the Cinebench suite. The PassMark results for the Core 9 include multithread score of 46107, single-thread score of 4573, integer math score of 164629, floating point math score of 125546, extended instructions score of 38743, data encryption score of 29636, data compression score of 585752, physics score of 2754, random string sorting score of 53167, and find prime numbers score of 198. These scores indicate a processor that handles a wide variety of computational tasks with high throughput. In comparison, the Intel Processor 300T has no recorded benchmark scores in the database. Its nearest rival data is also empty, so no percentile deltas or average score comparisons can be made for it. The Core 9's nearest rivals show how it stacks against other high-end processors: it trails the Intel Core Ultra 5 250K Plus by 1.1%, trails the AMD EPYC 4465P by 1.2%, trails the Intel Core Ultra 5 250KF Plus by 0.1%, and leads the AMD Ryzen 9 7950X3D by 0.3%. These small deltas place the Core 9 in a competitive tier with those chips. The Processor 300T, lacking any benchmark data, sits outside this comparison entirely.

Specification Differences

The two processors differ across nearly every core specification. The Intel Core 9 273PQE has 12 cores and 24 threads, while the Intel Processor 300T has 2 cores and 4 threads. Both have a base clock of 3.40 GHz, but the Core 9 boosts to 5.90 GHz, while no boost clock is listed for the Processor 300T. The TDP differs significantly: 125 watts for the Core 9 versus 35 watts for the Processor 300T. The L1 cache is identical at 80 KB per core for both. The L2 cache differs, with the Core 9 offering 2 MB per core and the Processor 300T offering 1.25 MB per core. The L3 cache is 36 MB shared for the Core 9 and 6 MB shared for the Processor 300T. Memory support is the same in terms of types, with both supporting DDR4 and DDR5, and both use dual-channel memory buses. The Core 9 has a recorded memory bandwidth of 89.6 GB/s, while no memory bandwidth is listed for the Processor 300T. ECC memory support is present on the Core 9 and absent on the Processor 300T. Both use the Intel Socket 1700, and both support PCIe Gen 5 with 16 lanes (CPU only). The integrated graphics differ: the Core 9 uses UHD Graphics 770, and the Processor 300T uses UHD Graphics 710. The Core 9 has a launch MSRP of $589, and the Processor 300T has a launch MSRP of $82. Both processors are locked, as neither has an unlocked multiplier. The Core 9 has part number SA4Q9, and the Processor 300T has part number SRN3K.

Architecture Differences

The Intel Core 9 273PQE uses the Bartlett Lake codename and belongs to the Core 9 (Bartlett Lake) generation. The Intel Processor 300T uses the Raptor Lake-S codename and belongs to the Intel Processor (Raptor Lake) generation. Both are manufactured by Intel on a 10 nm process node and both use the Intel Socket 1700. The Core 9 is a 12-core, 24-thread part, which indicates a high-core-count design suited to multi-threaded workloads. The Processor 300T is a 2-core, 4-thread part, indicating a minimal configuration for basic tasks. The cache hierarchies reflect the architectural gulf: the Core 9 provides 2 MB of L2 per core and 36 MB of shared L3, while the Processor 300T provides 1.25 MB of L2 per core and 6 MB of shared L3. The L1 cache structure is the same at 80 KB per core, but the overall cache capacity is much larger on the Core 9. The Core 9 includes ECC memory support, a feature absent on the Processor 300T, which points to different target markets. The integrated graphics differ as well, with the Core 9 using UHD Graphics 770 and the Processor 300T using UHD Graphics 710. The Core 9 has a recorded memory bandwidth of 89.6 GB/s, while the Processor 300T has no memory bandwidth figure recorded. Both processors support DDR4 and DDR5 memory over a dual-channel bus. The Core 9 was released in 2026, while the Processor 300T was released in 2024, so the Core 9 is a newer design. The Processor 300T has a recorded die size of 163 mm², while no die size is recorded for the Core 9. The Core 9's 125 watt TDP and the Processor 300T's 35 watt TDP further distinguish their architectural positioning: the former is built for performance, the latter for efficiency.

Where Each One Wins

The Intel Core 9 273PQE wins in every recorded performance metric. Its 12 cores and 24 threads give it a massive advantage in multi-threaded workloads such as video rendering, code compilation, and scientific computing. The Cinebench R23 multicore score of 39190 demonstrates this strength. The 36 MB shared L3 cache supports workloads that repeatedly access large datasets. The 5.90 GHz boost clock drives strong single-threaded performance, as shown by the Cinebench R23 single-core score of 5532 and the PassMark single-thread score of 4573. The Core 9 also supports ECC memory, which is valuable for workstations and servers that require error correction in memory. The 89.6 GB/s memory bandwidth further supports memory-intensive applications. Its nearest rival deltas, within 1.2% of several high-end chips, confirm it competes in the top tier of desktop processors. The Intel Processor 300T wins in power efficiency. Its 35 watt TDP is less than one-third of the Core 9's 125 watt TDP. For systems where heat output and power consumption are the primary constraints, such as compact desktops or always-on machines, the Processor 300T is the sensible option. Its 2 cores and 4 threads handle basic productivity, web browsing, and light office tasks. The UHD Graphics 710 provides display output without requiring a discrete GPU. The 6 MB L3 cache is small but sufficient for the workloads this processor targets. The Processor 300T belongs to the Raptor Lake generation, which is an established architecture. Its launch MSRP of $82 positions it at the entry level, while the Core 9's launch MSRP of $589 positions it at the high end. For users who need maximum compute capability, the Core 9 is the only choice between the two. For users who prioritize low power draw and minimal heat, the Processor 300T is the only choice. The database records no head-to-head benchmark wins for either processor, but the Core 9's extensive benchmark scores and 93rd percentile ranking versus the Processor 300T's 50th percentile ranking make the performance gap clear.
