CPU-only gaming value across five candidates

Performance comes from Tom's Hardware's table updated August 26, 2026: a score based on the geometric mean of 17 games at 1080p with an RTX 5090 FE, normalized to 9850X3D = 100. These are the outlet's measurements, not ours.

We calculate gaming score ÷ Japanese CPU price including tax × 10,000. Higher relative score per ¥10,000 ranks first; only the display is rounded to two decimals. Five of our seven price-checked candidates appear in this gaming table. The ranking does not cover the entire market.

Seven candidates with checked prices and availability

Prices were checked on September 12, 2026, between 13:23 and 13:31 JST. These are new-product Japanese retail examples; all displayed availability and dispatch within 24 hours. Preorders, used stock, points and coupons are excluded. Offers may change before you visit.

Dospara's shopping terms specify tax-inclusive listed prices, and Tsukumo marks tax inclusion on its product page. These offers are not claimed to be Japan's lowest prices. Check warranty handling, shipping, included accessories and the final payable total.

Turn the ranking into a shortlist

Use the 9600X as a starting point when preserving budget for a gaming GPU. For high-refresh play that needs more CPU headroom, inspect results for your games before excluding an X3D simply because its price-efficiency rank is lower.

The sampled 9850X3D costs ¥7,000, or about 9.6%, more than the 9800X3D. Judge that premium against your games, target frame rate and existing GPU. GamersNexus offers a separate measured comparison; its results are not merged into our ranking.

For frequent rendering, encoding or compilation, compare the 250K Plus and 270K Plus in benchmarks of your applications. A gaming score does not measure production speed, and adding P-cores and E-cores does not establish performance against another architecture.

Evaluate the 7500F and 9700X separately

At the sampled ¥26,667, the 7500F is a candidate for reducing AM5 CPU spending. AMD specifies six cores, twelve threads and a required discrete graphics card. It does not fit a plan to use only the motherboard's display outputs without buying a GPU.

TechSpot measured budget Ryzen 5 models including the 7500F, using a different test suite from our ranking source. We link that separate review for the budget decision instead of inventing a score to place the 7500F in this ranking.

The ¥47,320 9700X is a candidate when you want eight cores and sixteen threads on AM5, costing ¥7,520 more than the sampled 9600X. It is absent from the gaming table used here, so remains unranked; check whether it improves waiting times in your production applications.

Add a motherboard and 32GB of RAM

Replacing only the CPU and buying a new platform produce different bills. This budget example uses an ASUS B850M MAX GAMING WIFI at ¥19,980 for AM5 and a TUF GAMING B860M-PLUS WIFI at ¥25,980 for LGA1851. It is not a cheapest-build claim or a feature-matched motherboard comparison.

Both examples use the DosparaSelect D5D6000-16G2A1-RGB-BK 32GB kit, two 16GB modules, at ¥79,800. All three parts displayed stock and dispatch within 24 hours when checked at 13:26 JST on September 12, 2026. RAM is priced from that offer, not an older market assumption.

Totals exclude the GPU, SSD, cooler, power supply, case, OS and shipping. The CPU support lists cover these candidates, but we have not assembled these examples or guaranteed RAM operation at 6000. They also differ from the review's test systems.

Add a motherboard and 32GB of RAM
CPU	CPU only	With example board + 32GB
7500F	¥26,667	¥126,447
9600X	¥39,800	¥139,580
9700X	¥47,320	¥147,100
9800X3D	¥72,800	¥172,580
9850X3D	¥79,800	¥179,580
250K Plus	¥41,680	¥147,460
270K Plus	¥59,800	¥165,580

Check compatibility before upgrading an existing PC

If you can reuse a supported motherboard and RAM, the new-platform totals do not represent your actual upgrade bill. The Ryzen candidates use AM5; the Core Ultra candidates use LGA1851. Match the socket, then check the CPU support list's required BIOS against the board's shipping state.

Cooler inclusion, mounting hardware, RAM part number and module count also affect the purchase. Advertised XMP/EXPO clocks and CPU TDP alone do not establish stability, noise or real power consumption.

Record the existing CPU, motherboard model, BIOS version and RAM part number
Confirm that the CPU is listed and that you can reach the required BIOS
Check memory support, recommended slots and module-count conditions
Check cooler height or radiator clearance and mounting hardware
Remove reusable parts from the budget and add necessary cooling or update costs
Compare the remaining candidates for your GPU, games and applications

Recalculate when prices change

Price changes can reverse value positions. If the 9600X remains ¥39,800, a 250K Plus at ¥40,183 or less would lead this CPU-only metric. The break-even calculation is 73.3 ÷ 72.6 × 39,800.

That threshold excludes the board, RAM and cooler. For a new build, compare all required parts; for an upgrade, compare additional spending. Mixing scores from a different date or outlet changes more than the price input.

Record current new-product prices, stock and the check time
Keep gaming scores from the same table and test conditions
Divide the score by the tax-inclusive price and multiply by 10,000
Sort unrounded values, then review platform totals and your workload

Limits of the ranking and final purchase checks

An aggregate gaming result does not determine minimum FPS in one game or processing time in a production application. At GPU-heavy 1440p or 4K settings, spending more on the CPU may not produce proportional FPS gains. Preserve GPU budget for your target quality and resolution.

Before ordering, recheck the exact model suffix, new versus used condition, Japanese warranty handling, included cooler and dispatch estimate. After delivery, verify BIOS and memory settings, try your normal work, and use the same software, settings and method for any before-and-after comparison.

Limitations and requirements

Prices and stock are retail examples observed on September 12, 2026. Use the current checkout terms for any purchase.
The source outlet measured performance; we calculated price efficiency. We have not physically benchmarked these CPUs or assembled the example platforms.
The ranking covers gaming value for five selected candidates, not production performance, noise or the lowest prices across the market.

Frequently asked questions

Does the 9600X ranking first make the 9800X3D unnecessary?

First place refers to the gaming metric per unit of CPU spending. If you need higher frame rates or more CPU headroom, check 9800X3D measurements in your games and decide whether that benefit justifies the premium.

Why is the cheaper 7500F outside the ranking?

It has no score in the shared gaming table selected here. We avoid combining another outlet's measurements into the ranking and instead present its price and discrete-GPU requirement as a separate budget option.

Should I use the full platform total if I already own an AM5 board?

After checking BIOS, RAM and cooling compatibility, compare only the parts you actually need to buy. The examples with a new board and RAM illustrate spending for a new platform.
