QUOTE(ghoss @ Jan 17 2021, 10:30 PM) I'm also wondering that the overheat issue is memang like this since wanna push for higher speed? Apple A14 and Huawei Kirin 9000 overheats too...So far 5nm chip that doesn't overheat is huawei + apple  » Click to show Spoiler - click again to hide... « |

Actually from ARM's own expectation, the main benefit of this new chip (A78 and X-1) is the energy usage at same performance.
At the same performance, the energy consumption is reduced by 30-36%. At the same energy consumption, the performance increase is only about 7%. Some people mention that from actual gaming test it is consuming much more power at the same FPS compared to 865 chipset. IMO, this is due to the much higher clockspeed on the Adreno 660 (840MHz) compared to Adreno 650 (587MHz) to increase the performance by 35%. It should be a very similar architecture besides adding VRS support. We all know that (similar to PC GPU) the increase in power consumption is much more significant compared to the performance gained. Exynos 2100 will win in terms of CPU performance because their A78 is higher clocked compared to SD888 (while consuming much more power), but it will lose in terms of GPU performance compared to SD888. Power consumption is probably the same because Exynos2100 puts more budget on CPU whereas SD888 is higher clocked in GPU. Just my 2c. |

QUOTE(Max2006 @ Jan 21 2021, 01:13 PM) For people who prefer cheaper S21. It would be weird if they release 4G version though. The 5G modem is built-in to the Exynos 2100 chipset. Unless they purposely lock the 5G modem through firmware or create a separate chip. https://www.gsmarena.com/galaxy_s21_4g_vari...-news-47315.php Question: Will they release the 4G version in here since we already got the 5G version? Answer: Look at the S20Fe 5G and S20Fe 4G. Ya, Most likely....may be after few months later... They can do it for S20 FE because thr 5G modem is a separate chip. |

QUOTE(lambsauce @ Jan 24 2021, 11:34 AM) lmao exynos 2100 starting already at 4x fps only, last gen Mali gpu on mate 40 pro also better than it Mate 40 pro using Kirin 9000... its the same latest GPU as Exynos 2100 but with more cores. G78MP24 (kirin 9000) vs G78MP14 (EXY2100). ipohps3 liked this post

For those interested in the comparison of Sd888 and Exynos 2100 in more detail, can see this technical review from AT : https://www.anandtech.com/show/16463/snapdr...alaxy-s21-ultra
TLDR - SD888 is still more efficient compared to E2100 - E2100 is massively improved compared to E990 - Kirin 9000 and SD865 is very efficient compared to SD888 and E2100. SD865 chips can provide more sustained perf. - Kirin 9000 GPU is more efficient compared to E2100 (more cores & lower clocks?) - Samsung 5nm is comparable only to TSMC 7nm. Can't beat TSMC 5nm (by as much 20% difference). Hence why the lower than expected gains for SD888 compared to SD865. This post has been edited by Demonic Wrath: Feb 9 2021, 07:03 AM |

QUOTE(stevenryl86 @ Feb 9 2021, 09:05 AM) I thought tsmc vs samsung foundry debunked? From the test and Samsungs own number, it is still lacking by about 1 generation.QUOTE In least year’s review of the Galaxy S20 series and the Exynos 990 and Snapdragon 865 SoCs, an important data-point that put things into context was Qualcomm’s Snapdragon 765 SoC which was also manufactured on Samsung’s 7LPP node, and featuring Cortex-A76 cores. In that comparison we saw that The Exynos 990 and the Snapdragon 765’s A76 cores behaves very similarly in terms of power consumption, however they fell behind TSMC-based Cortex-A76 cores by anywhere from 20% to 30%. In that context, Samsung’s 5LPE process node improving power by 20% would mean they’d only be catching up with TSMC’s 7nm nodes. |
