Discussion Samsung Exynos 2400 SoC

[FlameTail]

Are there even any devices with 7 Gen 3? They announced it last November, but it was effectively a paper launch.

The only thing we have is this leaked benchmark:

Snapdragon 7 Gen 3 powered Honor 100 majorly disappoints in Geekbench debut

Qualcomm's new Snapdragon 7 Gen 3 SoC has shown up on the Geekbench 6.2 database. Its single and multi-threaded scores show minimal improvements over the Snapdragon 7 Gen 1.

The Samsung Galaxy A55 has just been announced.

Of interest is the processor powering it: The Exynos 1480

The 4nm Exynos 1480 processor powers the Galaxy A55. It has four high-performance Cortex-A78 CPU cores clocked at 2.75GHz, four power-efficient Cortex-A55 CPU cores clocked at 2GHz, and the Xclipse 530 GPU based on AMD's RDNA 2 architecture. It is said to have a 15% faster CPU and a 32% faster GPU

We don't know the full specs yet, as Samsung Semiconductor hasn't published it on their website.

I wonder how many RDNA3 CUs the Xclipse 530 has...

Also...WHY IS THIS THING USING THE ARM CORTEX A78

Why not any of it's successors... A710, A715, A720?

The Cortex A78 is a 4 year old CPU core!!!!

That's very easy to answer actually: A78 is the last core using ARMv8. All newer cores by Arm are ARMv9 which comes with a new licensing scheme costing about double the fees.

Samsung LSI already pays ARM for v9 license because they use the latest cores in their flagship SoCs.

If anything, this is shameful cost cutting by Samsung.

Licensing a v9 core doesn't mean they have a "v9 license". They likely used a Cortex-A78, which they already have licensed, because it reduces royalties.

Exactly. Shameful coat cutting. They even increased the price of Galaxy A55 with only minor YoY upgrades....

Also they don't lose much perfomance by using A78 compare to A710 or A715, E1480 perform same as sd 7 gen 3. It's like development of Android perfomance cores has stagnated, they only focus on prime cores nowadays.
