Intel Core i7-14700T vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The benchmark data records a decisive sweep. The Intel Core Ultra 9 285 wins all 17 head-to-head comparisons against the Intel Core i7-14700T, with no test going the other way. The margins, however, vary sharply by workload type, which reveals where each architecture's strengths and weaknesses lie.

The largest gap appears in PassMark's find prime numbers test. The Core Ultra 9 285 scores 459 against 145 for the Core i7-14700T, a 68.4% advantage. This test is highly sensitive to integer throughput and branch handling, and the results indicate a substantial generational uplift in the Core Ultra 9 285's execution engine.

PassMark extended instructions shows a 55.8% lead for the Core Ultra 9 285, with scores of 45357 versus 20052. This workload benefits from newer instruction set support and wider SIMD paths. Similarly, floating point math favors the Core Ultra 9 285 by 59.5%, scoring 194988 against 79042. The Core Ultra 9 285's wider vector units and higher clock ceiling appear to drive this outcome.

Data encryption delivers a 54.7% win for the Core Ultra 9 285, scoring 46949 versus 21277. The Core Ultra 9 285 also handles random string sorting with a 47.7% margin, 73651 against 38546. Both tests reward memory bandwidth and cache efficiency, areas where the newer platform demonstrates clear gains.

Cinebench results are consistent across the board. In Cinebench R23 multicore, the Core Ultra 9 285 scores 48945 versus 25980, a 46.9% lead. The same 46.9% delta appears in Cinebench R20 multicore, where it scores 20556 against 10911, and in Cinebench R15 multicore, 4933 against 2618. Single-core Cinebench results show a similar pattern: R23 single-core is 6909 versus 3667, R20 single-core is 2901 versus 1540, and R15 single-core is 696 versus 369, each a 46.9% to 47% advantage.

PassMark multithread shows a 46% lead for the Core Ultra 9 285, scoring 56602 against 30571. PassMark physics follows at 45.9%, with 3598 versus 1946. These results confirm that the Core Ultra 9 285's advantage is not limited to peak clock speed but extends into sustained multi-threaded throughput.

The narrowest margin is in PassMark single thread, where the Core Ultra 9 285 leads by 20%, scoring 4881 against 3905. Integer math is the second smallest gap at 30.9%, with 164869 versus 113854. Data compression sits at 41.2% in favor of the Core Ultra 9 285, scoring 602121 against 354216. The single-thread result is notable: despite the Core Ultra 9 285 having a higher boost clock, the 20% lead is smaller than the multicore deltas, which suggests that thread scaling and core count play a significant role in the overall margin.

Architecture Differences

The two processors come from different Intel design eras. The Core i7-14700T uses the Raptor Lake architecture on the Raptor Lake-R refresh, built on Intel's 10 nm process with a 257 mm² die. The Core Ultra 9 285 moves to Arrow Lake on the Arrow Lake-S platform, fabricated by TSMC on a 3 nm node with a 243 mm² die and 17,800 million transistors. The shift from Intel's own foundry to TSMC for the compute tile is a major structural change between generations.

Core and thread counts differ in an important way. The Core i7-14700T has 20 cores and 28 threads, meaning it uses Hyper-Threading to reach 28 threads from 20 physical cores. The Core Ultra 9 285 has 24 cores and 24 threads, with no Hyper-Threading. The Core Ultra 9 285 therefore has four more physical cores but four fewer threads in total. Despite the lower thread count, the benchmark data shows the Core Ultra 9 285 winning every multithreaded test, which indicates that its per-core performance advantage more than compensates for the missing threads.

Clock speeds also favor the Core Ultra 9 285. The Core i7-14700T has a base clock of 1.30 GHz and a boost clock of 5.20 GHz. The Core Ultra 9 285 runs at a 2.50 GHz base and boosts to 5.60 GHz. The higher base clock is particularly relevant for sustained workloads, while the boost clock advantage contributes to single-thread performance.

Cache hierarchies have grown substantially. The Core i7-14700T provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Core Ultra 9 285 increases L1 to 192 KB per core, L2 to 3 MB per core, and L3 to 36 MB shared. The larger per-core caches align with the wider execution resources of the Arrow Lake design.

Memory support changes completely. The Core i7-14700T supports both DDR4 and DDR5 in a dual-channel configuration. The Core Ultra 9 285 supports DDR5 only, also dual-channel, but with a recorded memory bandwidth of 102.4 GB/s. The Core i7-14700T has no recorded memory bandwidth figure in the database. The move to DDR5-only simplifies the memory controller and enables the higher bandwidth.

The integrated graphics differ as well. The Core i7-14700T uses UHD Graphics 770, while the Core Ultra 9 285 uses Arc Xe-LPG Graphics 64EU. PCIe connectivity also improves: the Core i7-14700T offers Gen 5 with 16 lanes from the CPU, while the Core Ultra 9 285 offers Gen 5 with 20 lanes. Both processors support ECC memory and both are locked, with no unlocked multiplier.

The sockets are incompatible. The Core i7-14700T uses Intel Socket 1700, while the Core Ultra 9 285 uses Intel Socket 1851. This means a platform change is required to move from one to the other, regardless of performance considerations.

The TDP difference is substantial: the Core i7-14700T is rated at 35 W, while the Core Ultra 9 285 is rated at 65 W. The Core i7-14700T is clearly positioned for lower-power systems, while the Core Ultra 9 285 targets higher sustained performance. Both processors are locked, neither has an unlocked multiplier, and both support ECC memory.

The Verdict

The benchmark data leaves no ambiguity about raw performance. The Intel Core Ultra 9 285 wins every recorded test, with leads ranging from 20% in PassMark single thread to 68.4% in PassMark find prime numbers. The average benchmark score tells the same story: the Core Ultra 9 285 averages 75488, while the Core i7-14700T averages 41914. The Core Ultra 9 285 sits at the 95th percentile of all CPUs in the database, while the Core i7-14700T sits at the 88th percentile.

The Core Ultra 9 285's nearest rivals in the database are server-class AMD EPYC parts, including the EPYC 8224P with an average score of 75582 and a 0.1% delta, the EPYC 4545P at 75373 with a 0.2% delta, and the Ryzen 7 PRO 9755X3D at 75716 with a 0.3% delta. The Core i7-14700T, by contrast, competes with mobile and mid-range desktop parts: the Ryzen 9 PRO 8945HS at 41963 with a 0.1% delta, the Core i7-12850HX at 41779 with a 0.3% delta, and the Ryzen 5 7400 at 42055 with a 0.3% delta.

The Core i7-14700T remains relevant for scenarios where its 35 W TDP and DDR4 compatibility matter. It is the only one of the two that supports DDR4, which can matter for systems reusing existing memory. Its 28 threads also outnumber the Core Ultra 9 285's 24 threads, though the benchmark data shows that thread count alone does not translate into a multithreaded win.

The Core Ultra 9 285 is the choice for anyone prioritizing peak performance across every measured workload. It delivers higher clocks, more cores, larger caches, newer process technology, and higher memory bandwidth. The 65 W TDP is double the Core i7-14700T's rating, but the performance return is visible in every category. The data indicates that the Core Ultra 9 285 is in a different performance class, one that places it alongside server processors rather than mid-range desktop parts.
