The MediaTek Dimensity 9400 is making waves in the tech community, especially with its impressive AnTuTu score of approximately 3,449,366. This flagship chipset promises exceptional performance, making it a strong contender against Qualcomm's Snapdragon series. With a powerful Arm Cortex-X925 core running at 3.62 GHz, users can expect up to 35% faster single-core performance and 28% faster multi-core performance compared to its predecessor.But is the MediaTek Dimensity 9400 good? Absolutely! Its combination of advanced graphics capabilities via the Immortalis-G925 GPU and superior AI processing features positions it as a top choice for gamers and multitaskers alike.Several upcoming smartphones are set to feature this chipset, including the Oppo Find X8 Pro 5G, Vivo X200 Pro 5G, and Samsung Galaxy S25, among others. With a price point around $155, it offers great value compared to competitors.As we await more devices powered by this innovative technology, the MediaTek Dimensity 9400 is poised to redefine user experiences in mobile technology. What are your thoughts on this chipset? Are you excited about the phones it will power?

The Dimensity 9400 is a beast when it comes to multi-core CPU performance. It easily outshines the Snapdragon 8 Gen 3 and A17 Pro, and what’s impressive is how it manages to stay super energy efficient while doing so. This means better battery life without sacrificing performance. Sure, it may not quite match the A18 or A18 Pro in single-core tasks, but for most users, the Dimensity 9400 is still a powerhouse in multi-core performance and overall efficiency. Honestly, I’m really excited to see how phone makers use this chip in upcoming devices!

Media tek is getting a little too big for their britches,
They used to offer more specs than the competitor but now they seem to offer about the same, for example
My Motorola edge 2022 has the dimensity 1050 AKA MT6879. That ship has 5G capabilities almost as close to their current flagship in regards to it having 3CC 5g and 200mhz of bandwidth.
And the 1050 was considered a mid-range chipset, with the 865 Qualcomm w/ x55 being a bit more powerful but had way less 5G capability. (1cc)
Basically to get something like 3cc back when the 1050 was new you would need to jump to qualcomm's flagship like the 888 or SGen 1, etc , granted Sg1s (x65,x70, etc ) has 300mhz+.
Now since the mediatek seems to have a bigger market share they have now stopped offering the extra 5G capabilities that they used to offer in their chipsets, to entice buyers and such.
Anything in the 9,000 series offers 3CC 5G with 300mhz.

At 12 watt power usage, A18 Pro dominates, being followed closely by the A18, and Dimensity D9400. It's impressive Apple does that with only 6 cores, while MediaTek uses 8.
De GPU curve is even more interesting. In 3DMark SNL the Dimensity 9400 totally dominates, even over the A18 Pro. Isn'tt even close, 25% faster than A18 Pro, or doing the same performance at 7 watts instead of 13 (almost half the power).
Adromedae@reddit
Yup. Apple's big and small out-of-order cores are just on a league of their own. Really impressive the level of microarchitectural dominance Apple has maintained for so long.
Really wish they would commercialize their cores as discrete parts of linux applications ;-)
And M4-level big ARM core + an beefy NVIDIA GPU would be a dream workstation for some of the type of use cases I work with!
DerpSenpai@reddit
Apples little cores are just 10% more efficient than the A720, same performance on the D9400.
Own-Chemistry-2722@reddit
I disagree with your logic there.
DerpSenpai@reddit
yeah, in SPEC the A18 has a bigger lead so even in nT Apple wins it. we got more data now
Vince789@reddit
Yea, it's impressive Arm are closing the gap in little cores rapidly. The A725 should have an uplift vss the A720 in the D9400
Yea, GB6 MT tries to be more "real world MT" than "embarrassingly parallel MT". GB5 MT was more like "embarrassingly parallel MT"
Geekerwan also have the A18P vs older D9300+ results for GB5 MT. Basically the same performance, but the A18P uses ~13W vs the D9300+'s 17.5W
At ~13W in GB5 MT, the D9400 probably has a decent lead over the A18P considering the D9400's improvement over the D9300+, which makes sense since its 2+4 vs 1+3+4
DerpSenpai@reddit
Yeah considering the little cores have sameish performance
1 X925 corre + 3 X4 cores obviously have much faster MT than 2 Apple P cores
Adorable_You_7725@reddit
There gpu has 12 cores and hole apples has 6 if apple added 12 it basically would be super good but
Own-Chemistry-2722@reddit
It will have to implement a strong cooling solution like I expect with the A19 pro (iPhone 17 pro)
Own-Chemistry-2722@reddit
Don’t know what these tests are but the a18 pro still beats the 9400 in single and multicore cpu benchmarks (link below). As far as gpu….The snapdragon 8 gen 4 and dimensity 9400 are gonna HAVE to have some kind of super advanced active cooling solution or they will MASSIVELY throttle …and sustained gaming while pushing the gpu will last maybe 10 minutes. I imagine apple will be working on a cooling solution for their next phone as well if they wanna stay in the competition.

Darkknight1939@reddit
Since Samsung went for Mediatek on the Tab S10 series, I wish they would've waited a couple months for the 9400.
TwelveSilverSwords@reddit
Geekerwan's socpk website is great. We can view all the power curves they have tested and compare them...
But only mobile SoCs. When will they add laptop SoCs? That would be cool.
Adromedae@reddit
Yeah. It's refreshing to finally have a reviewer with a modicum of understanding of what they are reviewing and proper methodology.
Abject_Radio4179@reddit
They’re good, no question about it. But I always cringe when I see their IPC charts, as they don’t measure instructions per clock but performance per clock. And it gets even more cringeworthy when they assume that IPC is frequency independent whereby they do a great disservice to the community.
Adromedae@reddit
Yeah. A lot of people miss that (thermal) throttling and memory subsystem performance do affect IPC, and they are both frequency correlated.
But then again, most people know fuck all about microarchitecture.
DerpSenpai@reddit
Geekerwan should partner with a western publication to help with translation and putting their work out there here in the west. He does the best work and should be compensated for it. he even has industry connections to get samples early.
Vince789@reddit
Agreed, just wish they'd add their SPEC power curves, SPEC energy efficiency (joules not power), and GB ST power curves
DerpSenpai@reddit
Spec power curve is impossible. It takes too much time
Vince789@reddit
I'd thought so too, but they've added SPEC power curves to their LNL & D9400 reviews on YouTube
https://x.com/lafaiel/status/1841549633539252320?t=oIya7cDNS2nB5T79gkasDA&s=19
Although there's a (translation?) error with calling them energy efficiency curves (instead of power efficiency curves)
RegularCircumstances@reddit
Efficiency should really be measured on a per-core basis. The MT below certain power segments isn’t useless per se, as it’s true a phone able to split up the tasks with more E Cores at lower clocks can save energy for the same speed (a hypothetical 2+2 Apple chip would be slower or less efficient for instance in some use) but ultimately most phones have roughly enough cores for background tasks or tabs etc.
So again I think just comparing the ST curves across integer benchmarks and the same for the e core is the most functionally relevant comparison.
Stennan@reddit
Dimensity 9400 has an integrated modem like the Sanpdragons right? Wish I knew more or could find more info, but my understanding is that integrated modems inside the SOC are more efficient for standby time. Googles Tensor chips have an external modem if I'm not mistaken?
PMARC14@reddit
Yes an integrated modem can be more efficient for standby time. Mediatek and Qualcomm have the current best modems, on-die. Samsung is just behind, and Google uses a Samsung Modem as a separate component. Apple also uses a significantly older Qualcomm modem as a separate component and has the worst raw performance.
Dreamerlax@reddit
Going off the iFixit teardown. The current Tensor (at least) has a discrete modem
https://www.ifixit.com/Guide/Google+Pixel+9+Pro+XL+Chip+ID/176196
Dimensity is integrated.
Famous_Wolverine3203@reddit
Isn’t this the most useless metric for mobile phones though.
I’m way more interested in the Single thread curve.
Creative_Purpose6138@reddit
Mediatek made a mistake not including A520 cores, you cannot beat the power curve for low intensity tasks. And LAST YEAR's X4 cores?! WTF! At least put higher clocked A725s or lower clocked X925s. They are scamming customers.
signed7@reddit
Wow A18/A18 Pro is a huge gen-on-gen leap over A17 Pro (which barely improved over A16 in comparison)
