A split-screen graphic compares AMD Ryzen and Intel Core Ultra processors, with gaming and creative-work setups in the background.
The Ryzen 7 9850X3D is the faster gaming chip. The Core Ultra 7 270K Plus is the faster chip for heavily threaded work, and it costs less. That is the verdict of TechRepublic's October 8 comparison. AMD's eight-core X3D chip is the stronger gaming CPU, while Intel's 24-core hybrid processor delivers substantially more multi-threaded performance for considerably less money. The details below decide which one suits a given build.

Intel's own specification page confirms the 270K Plus figures. They include 24 cores (8 Performance and 16 Efficient), 24 threads, 36 MB of Smart Cache and 40 MB of L2. The page lists a launch date of Q1 2026. It also lists a recommended customer price of $339 to $349, so the $349 figure is the top of a range.

Intel's launch announcement, dated March 11, 2026, said the chip adds four more E-cores over its predecessor. It also described a higher die-to-die frequency and support for DDR5-7200. Intel quoted a starting suggested price of $299 at that time, which is well below today's listed range. Prices have clearly moved since launch.

Gaming: AMD's cache wins​

Tom's Hardware's CPU hierarchy was last updated October 5, 2026. It names the 9850X3D the fastest CPU on the market in games. It also notes that Intel's 270K Plus lands slightly behind Intel's own last-generation Core i9-14900K there, with the help of Intel's Binary Optimization Tool.

In TechRepublic's summary of that ranking, the 9850X3D is normalized at 100% and the 270K Plus scores 77.5%. That puts AMD about 29% ahead. TechRepublic also says PCWorld measured the 270K Plus about 25.5% behind in Cyberpunk 2077, 25.8% behind in Rainbow Six Siege X, and 34.5% behind in F1 2024.

These gaps are not a promise for every PC. CPU differences show up most at lower resolutions, high frame-rate targets and with a fast GPU. If you play at 4K with a mid-range graphics card, the GPU limits performance and the gap narrows. A third-party aggregator, howmanyfps, reports a 45% gaming lead across 100+ games. Its methodology differs from Tom's, so treat it as a rough cross-check. Different suites give different numbers, but all of them favor AMD in games.

The 9800X3D question​

The 9850X3D is a small step over the 9800X3D. GamersNexus, in its January review, found it was at best 4% faster and sometimes identical. It also measured a few trade-offs:

  • Temperatures were about 7 to 9 °C higher (roughly 83 °C versus 74 to 75 °C) with the same 360 mm cooler.
  • Power through the EPS12V cables was 164 W versus 143 W for the 9800X3D.
  • It launched at about $500, which is $20 to $50 more than the 9800X3D.

GamersNexus's verdict was that the chip is hard to recommend over the 9800X3D unless you want a possibly better overclocker. Owners of an existing X3D chip should read this as a reason to skip the upgrade.

Productivity: Intel's core count wins​

Intel leads once a workload can use many cores. Tom's multi-thread ranking has the 270K Plus at 91.9% against 54.8% for the 9850X3D, about 68% ahead. Tom's hierarchy text also says the 270K Plus tops its single-threaded chart and is third in multi-threaded, behind only the Ryzen 9 9950X and 9950X3D. Those two chips cost roughly twice as much.

PCWorld, as cited by TechRepublic, found the Intel chip about 65% faster in Cinebench 2026 multi-core. It also found 67% to 72% leads in Blender. A third-party database, TopCPU, shows a similar Cinebench 2026 multi-core lead of about 76%. Single-thread leads are much smaller. Tom's has Intel at 100% against 93.2% for AMD, while CPU-Monkey shows roughly 96% for Intel against AMD's 100%.

Two caveats apply:

  • Not every application scales across 24 cores. Photoshop, game engines, compilers and encoders all behave differently, so check benchmarks for the software you use.
  • The 270K Plus has no Hyper-Threading. Intel's spec page lists it as "No", so its 24 threads equal its 24 cores.

The Intel chip also has Quick Sync Video and an NPU rated at 13 TOPS, per Intel's spec page. That page lists WindowsML, DirectML, ONNX Runtime and OpenVINO among the supported AI frameworks. The NPU only matters if your software uses it.

Power and cooling​

The official ratings are 120 W for AMD and 125 W base (250 W max turbo) for Intel. TDP is not real power draw, as GamersNexus itself points out. In its testing:

  • The 9850X3D drew about 164 W through the EPS12V cables in an all-core load.
  • The 270K Plus showed 230 to 251 W of CPU package power in Blender, according to TechRepublic's account of GamersNexus's results.
  • An external reading of about 284 W also includes VRM losses and other motherboard power, so it is not comparable with AMD's figure.

Neither chip includes a cooler. Budget for a capable cooler, and consider a 360 mm liquid cooler for the 9850X3D, which AMD recommends.

Platform, upgrade path and memory​

AMD has committed to supporting AM5 through 2029, per TechRepublic. If you already own a compatible AM5 board, the 9850X3D may be a drop-in upgrade after a BIOS update. Intel says the 200S Plus chips work in all 800-series motherboards currently on the market. It has not given a multi-year socket timeline like AMD's.

On memory, Intel's spec is higher on paper. Those are official controller ratings, not hard limits. EXPO and XMP profiles can exceed them. For Ryzen, DDR5-6000 is a common practical target.

Cost: look at the whole build​

TechRepublic's snapshot on October 8 had the 9850X3D at $499 at Best Buy and the 270K Plus at $330 at Newegg. That is about $169 apart. Two MSI boards it cited, the MAG B850 Tomahawk Max WiFi II and the MAG Z890 Tomahawk WiFi, both list at $259.99. Two boards don't set a trend, so price the full CPU, motherboard, RAM and cooler combination yourself. Retail prices change daily, so confirm them before buying.

Which should you buy?​

  • Gaming-first PC with a high-end GPU: the 9850X3D.
  • Rendering, compiling, encoding or mixed use on a budget: the 270K Plus. The savings can go toward a better GPU, SSD or cooler.
  • Existing AM5 owner on a 7000-series chip: the 9850X3D is a strong upgrade. Check your board's BIOS support first.
  • Already own a 9800X3D: don't bother.

One caution on sources. TechRepublic carries affiliate disclosures, and Intel's performance claims come from its own testing. Independent reviewers have generally found the gaming gap to be wider than Intel's figures suggest, which is why this comparison leans on Tom's, PCWorld and GamersNexus.
