Discussion Samsung Exynos 2400 SoC

[FlameTail]

Does RDNA (or atleast RDNA as impmented in Exynos SoCs) have tile-based rendering?

If not, this is going to be a problem, as tile based rendering is more power efficient and less bandwidth hungry- crucial qualities to have in a mobile GPU.

The only thing this tells me is that if a phone can have 12CU RDNA3 then AMD APUs are extremly underpowered.

Are they running at the same clocks though?

No.

Did anyone like Geekerwan get to measure the efficiency of this SOC?.

I remember Andrei and Golden Reviewer going back and forth on how Golden Reviewer’s measurements are garbage. So don’t know how reliable his data is

Well, all things considered in real world usage it's not great:

There were some mutterings that Geekerwan will not make a dedicated video for E2400 in either hid English or Chinese, but he will do the benchmarks/power measurements and upload them to his website- socpk.

I saw that video and there is huge possibility those phone didn't connect at same band, check signal quality one is close to full bar and other is barely half.

It's very common that Samsung modem has worse power efficiency and worse signal. GSMArena call test also shows that (when compared against S23).

Samsung modems in Google Pixel phones are potatoes.

Same with Tensor, i wish they had data for these SoCs

Geekerwan has previously tested the Exynos 2200 and OG Tensor chip. You can find those curves in his English Channel video about Power Efficiency.

However, since then he has not tested any Exynos or Tensor chip, nor have the results been uploaded to his website.

They never fail to disappoint, sadly.

Yes but S24 ultra review also show dropping in Call score.


Same battery size it drop from 39H to 35, also if you adjust battery size difference between S24 ultra and s24/s24+ isn't much.

Problem with that video is two different networks were connected I researched it and you can see what those icons mean here

One device were connected to 5G and another device were connected to hybrid network with both 4G and 5G, whatever that guy said he is lying.

Samsung modem in Pixel is external modem, not included in soc, most of time external modem use more power, not just Samsung when 5G came out Qualcomm soc with external modem were power hungry too.

SD865 is paired with an external modem, and it was a very decent SoC. The TSMC node probably helped, as it's successors moved to Samsung for 2 following generations.

True but at that time there was lot of noise on how 5G eat lot of battery,

How much more power does 5G consume over 4G? Redmi has answer

5G phones generally consume more power than 4G phones, but just how much more? Redmi has shed some light on battery life comparisons.

www.androidauthority.com

Redmi CEO claimed 5G increase power by 20% compare to 4G, when announcing redmi K30 pro (sd 865 device)

 

[Doug S]

The newer cellular standards always require more power because they support more complex encodings and more bands, and because they support higher speeds people tend to use more data. i.e. when 5G was new and most people were on LTE the LTE might be slow which will discourage use of it (or encourage people to seek out wifi if it is available) but 5G bands were uncongested so people would use it a lot more (at least within the bounds of their data limit if they weren't unlimited)

I've never seen it, but I wish we'd see comparisons between LTE and 5G downloading the same amount of data over the same band (which doing tests with a carrier supporting DSS could provide) I suspect that any difference would be within the margin of error for repeated tests.

S23 vs. S24 difference is on another level and S24 even has larger battery.

Could be that S8G3 isn't as efficient or they haven't optimised it properly since S23+ can do 36:26h. Even still, Exynos is behind.

 

[Apokalupt0]

We might see some measurements from Geekerwan soon.

Samsung Exynos 1480 SoC leaked.

This SoC will have an AMD RDNA iGPU. First time in a Midrange Exynos.

The CPU performance is disappointing. This SoC will go into the Galaxy A55 launching this year, which will be priced at ~$450.

For that price, there a lot of alternatives with Mediatek or Qualcomm processors with much stronger performance.

Atleast I wish Samsung put in a Cortex X core in these 1x80 series Exynoses.

Their OneUI software skin is quite heavy, and strong ST performance is essential to run it smoothly.

For A5X audience that's soc is perfect, if they put X core there what's the point of FE series?

For A5X audience that's soc is perfect, if they put X core there what's the point of FE series?

IMO FE line shouldn't exist at all.

What Samsung should do is sell the last year's base S model for the FE price point.

Example for 2024:

S24: $800
S23: $650
A55: $500

A5x is one of Samsung's best selling phones


Hence, Samsung should ensure their customers get a good experience, by putting X core in the SoC.

It is necessary, because as I explained, Samsung's OneUI skin is quite heavy. Hence, strong ST performance is essential for smooth and snappy performance.

Take the Pixel 7A for comparison. It can be found in the same price range as A54. But it is much smoother and snappier than A54 thanks to the Cortex X core (and the lighter Pixel skin on top).

The A5x line has always shipped with underpowered SoCs.

A51: Exynos 9611
A52: Snapdragon 750G
A53: Exynos 1280
A54: Exynos 1380

All these SoCs were weak for their time and price point. The only outlier is the A52s 5G, which shipped with the 778G.

This has become problematic over time, as the A5x line has risen in price, and especially as last year, Samsung discontinued the A7x line. Which means, the A5x is now the premier of the A series.

With midrange you always have to make sacrifices, your graph shows why Samsung is Right, A54 was among top seller, because it offer all around features other midrange don't offer.

There are dozens of midrange with top perfomance but lack in features, they don't sell much because it's niche market, only Enthuasist buy those, Average user want Good Display, Camera, Water resistant, Good build quality etc.

So Samsung made two model A5X which give you good enough perfomance with premium features targeting average users and FE series which has old Flagship soc targeting power users.

Also Exynos 1480 is Equivalent of Snapdragon 7 gen 3 which is successor of snapdragon 778G, if you regard 778G as good soc then 1480 is worthy successor.
