Dimensity 7300 Ultra vs Dimensity 7300X: Specifications, Naming and Benchmark Evidence

MediaTek’s published specifications for the Dimensity 7300 and Dimensity 7300X describe the same CPU layout and the same Mali-G615 graphics family. The practical difference is design intent: MediaTek positions the 7300X for flip-style foldables with two displays. The sources available do not establish “Dimensity 7300 Ultra” as a separate MediaTek chip, and no controlled benchmark compares the two chips directly, so no performance winner can be named.

Is “Dimensity 7300 Ultra” a real chip name?

Not as an official MediaTek product. The sources reviewed for this comparison do not establish a chip called “Dimensity 7300 Ultra” that sits apart from the Dimensity 7300.

The label appears in two places, and they disagree:

• Motorola Support India lists the processor of the Edge 50 Neo as “MediaTek Dimensity 7300.”
• PassMark’s Android device page for the same phone labels its CPU “Mediatek Dimensity 7300-Ultra (MT6878).”

The most likely reading is that “Ultra” is a benchmark database’s naming choice for one phone’s processor, not a model tier MediaTek markets. Treat it as a label, not a verified product. If you see “7300 Ultra” in a listing, check the manufacturer’s own specification page for the exact model and region before assuming it refers to a different silicon version.

#1 Best Overall

AGM G3 Pro Flagship Rugged Phone, 512x384 25fps Thermal Camera, 24GB+512GB

• PROFESSIONAL THERMAL VISION | The 512x384 thermal camera combines smooth 25fps imaging with 40mK thermal sensitivity to reveal subtle heat differences during electrical checks, HVAC diagnostics, engine inspections, building maintenance and repairs. With dual temperature ranges reaching up to 550°C, G3 Pro puts a serious thermal tool directly in your phone for troubleshooting and field work
• T-MOBILE CONNECTIVITY | Designed for compatible T-Mobile service in the U.S., G3 Pro android phone supports 5G where available, 4G LTE, Dual Nano SIM and Dual Standby for flexible work, personal and travel use. Fast mobile data keeps navigation, cloud files, video calls and field apps moving, while NFC and multi-satellite positioning add useful support for payments and navigation
• FAST PERFORMANCE, SERIOUS STORAGE | The 4nm MediaTek Dimensity 7300 pairs 12GB physical RAM with up to 12GB memory expansion for responsive multitasking across maps, reports, streaming and everyday apps. 512GB built-in storage plus up to 1TB expandable space gives you room for thermal records, photos, video and offline files, while the 6.72" FHD+ 120Hz display keeps scrolling and navigation fluid
• 10000MAH POWER, FLEXIBLE CHARGING – Built for long shifts, road trips, navigation and extended days away from a charger, the 10000mAh battery delivers serious endurance while the approximately 375g body keeps G3 Pro more manageable than many extreme-battery rugged phones. Recharge with 33W USB-C PD, use 18W wireless charging, or share power through reverse charging with compatible devices
• BUILT TOUGH, LOUD AND READY OUTSIDE | IP68/IP69K protection and MIL-STD-810H durability help G3 Pro handle rain, dust, mud, drops and demanding jobsite conditions, while the powerful 116dB speaker keeps calls, alerts and navigation easier to hear in noisy surroundings. A built-in camping light, 64MP Sony main camera, 50MP front camera, OTG and 3.5mm audio add practical tools for inspections, night tasks, work records and outdoor use

Official specifications side by side

MediaTek announced the Dimensity 7300 and 7300X together on May 30, 2024, as related 4nm chips. The table below separates what MediaTek’s announcement states from what its 7300X product page adds. Where a value appears only for the 7300X, the 7300 column reads “not stated” because the sources reviewed do not give it for the 7300.

These are system-on-chip capability figures. A phone maker decides which memory, storage, display and wireless options a handset actually uses, so a figure in the table is a ceiling for the chip, not a promise for every device built on it.

What the 7300X adds: foldable and dual-display design

The clearest difference between the two chips is the form factor MediaTek says it was built for. In its May 30, 2024 announcement, MediaTek’s Dr. Yenchi Lee, Deputy General Manager of its Wireless Communications Business, said: “Furthermore, the Dimensity 7300X enables OEMs to develop innovative new form factors thanks to its dual display support.”

That quotation describes design intent from the vendor. It is not an independent evaluation of how well dual-display phones perform. The 7300X’s display-mode figures show what the chip can drive; whether a given flip phone uses its second screen, and how, is up to the manufacturer.

Example phones: what the listed chip does and does not tell you

Each chip is paired with a specific handset in the sources reviewed. These phones illustrate the design; they are not a measure of the chip.

Phone-level traits such as display size, battery and camera setup come from the handset, not the chip. Regional versions of the same model can also differ in memory, storage or other configuration, so check the page for the exact market you plan to buy in.

Benchmark evidence: what exists and what it cannot show

No controlled, directly comparable benchmark of the Dimensity 7300 against the Dimensity 7300X turned up in the sources reviewed. The only measured figures available are device-level aggregates from PassMark’s Android Benchmark pages.

PassMark’s Edge 50 Neo aggregate

PassMark states that its device results draw on thousands of PerformanceTest Mobile benchmark results and update daily. Its page for the Edge 50 Neo shows the following values:

These numbers describe one phone as submitted by users, not the Dimensity 7300 as a chip. Memory, cooling, firmware and thermal behaviour all shape a phone’s score, and the page’s comparison section was dated June 29, 2026, so the values can change. The page contains no Dimensity 7300X phone, so it cannot rank the two chips.

What a valid head-to-head would require

• The same handset model, or at least devices with matching memory, storage and firmware, tested under the same conditions.
• Several runs per device, with the spread reported rather than a single score.
• A named benchmark and a stated methodology, so the result can be repeated.
• Results labelled by device or by chip, with the distinction made explicit.

Until a test meets those conditions, any claim that one chip is faster than the other goes beyond the evidence.

MediaTek’s efficiency and performance percentages

MediaTek publishes percentage claims for both chips, and they are easy to misread as a measured gap between them.

• May 30, 2024 announcement: 20% faster FPS and 20% improved energy efficiency compared with “competitor alternatives,” plus 13% to 30% greater power efficiency in common sub-6GHz 5G scenarios. The announcement does not name the competitors or describe a test method.
• 7300X product page: up to 20% greater FPS and up to 20% improved energy efficiency versus competitor alternatives for gaming, and 13% to 30% greater power efficiency for common 5G scenarios.

These are vendor claims about MediaTek silicon against unnamed rivals. They do not measure the 7300 against the 7300X, and they should be attributed to MediaTek whenever they are repeated.

How to choose between the two

The published CPU and GPU specifications match, so the phone you buy will mostly be defined by its other features. Use this order when you compare:

1. Decide whether you need a second screen. If you want a flip-style phone with two displays, the 7300X is the chip MediaTek designed for that layout, and you should confirm that the specific handset uses it.
2. Open the manufacturer’s specification page for the exact model and region, and read the chip name there rather than relying on a retailer listing or a benchmark label.
3. Compare memory and storage configuration, display, battery, camera and software update commitments for each model, since these vary more between phones than the chip does.
4. Check benchmark entries only for the exact model you are considering, and read them as device averages rather than chip rankings.

If you do not need a dual-display design, the choice between a 7300-based and a 7300X-based phone should rest on the handset, not the chip name.
