Samsung Galaxy S21 ultra review

Hello friends welcome to Hindibloganish.com today I am going to ( today I am going to Review Samsung Galaxy S21 ultra  )}

The Galaxy S21 lineup will be launched intwo months from now on and hence it's making quite a lot of headlines lately. We have tons of new information about thehandset today starting with some case leaks. Third-party companies have manufactured differenttypes of cases for the S21 lineup, specifically, we have a couple of folio cases for the S21and Ultra. Interestingly it shows the S21 Ultra with4 rear cameras which isn't the case anymore. 


Samsung has updated the design, now it willhave 5 rear cameras. We know what those 4 cameras are going tobe but still, there's a mystery surrounding that fifth camera setup. But it seems we finally know what it couldbe. Samsung has made ISOCELL Vizion 33D officialyesterday which is an updated time of flight sensor that goes toe to toe with Apple's LIDARsensor.

This new sensor is can assist in AR/VR experiencesas well as 3D scanning and video bokeh effects. On top of that, it has an exceptional autofocusingwhich explains why we don't see a laser autofocus sensor in Onleaks' cad renders. So even though it isn't official but we canalmost be certain that the fifth camera on the S21 Ultra is this ISOCELL Vizion 33D sensor. 

Moving on, we have specifications of Snapdragon875 that will go inside the S21 lineup. As per this tipster who has been right multipletimes, the Snapdragon 875 has one Arm Cortex-X1 prime core clocked at 2.84GHz, three Cortex-A78performance cores with clock speeds of 2.42GHz, and four Cortex-A55 efficiency cores runningat 1.8GHz. The chipset will be built on the 5nm processand reports suggest that Samsung will be making it for Qualcomm. 

Now it's good news for folks over in the USand Canada that Qualcomm is using Cortex X1 prime core for the 875 which offers a 30%performance boost over the prime core of the 865. Now, this also is good news for Exynos regionsbecause they will get identical performance this time because Exynos 2100 will also usethe same cluster of cores as Qualcomm. Samsung might go for a higher GHz clock speedfor Exynos 2100 and if that's the case then Exynos 2100 will give better CPU performancethan Snapdragon 875. 

Anyway, now that both chipsets are expectedto offer similar CPU speeds, the difference will come down to GPU speeds. And interestingly Samsung might get the lastlaugh if they go down Huawei's route. Because we have benchmarks of Huawei's latest5nm chip the Kirin 9000 and Snapdragon 875, which shows that Mali GPU has finally managedto beat Adreno of Qualcomm. This is from a Chinese benchmarking platformMaster Lu which shows the Snapdragon 875 scored 333,269 on the CPU test and the Mate 40 Pro'sKirin 9000 achieved 275,862 points. 


It was expected since Huawei is using a yearold Cortex A77 vs the latest A78 and the mighty X1 cores on the 875. But the shocker is GPU speeds as Snapdragon875 apparently managed to get 342,225 on the GPU test, which puts it behind the Kirin 9000which achieved 344,334. Huawei even mentioned that its chipset's graphicsperformance is 52 percent faster than the Snapdragon 865 Plus, and it now appears thateven with the introduction of the new Adreno GPU, it will maintain a lead. Exynos 2100 will also use the same Mali G78GPU so Samsung could surprise everyone this time and beat Qualcomm even in GPU. 

But there's a catch, this new Mali G78 comesin two configurations, One with 18 cores and another with 24 cores. Huawei used 24 cores for maximum performancebut the problem is it consumes a lot of power. The 18 core is more energy efficient but doesn'tprovide the same level of performance as the 24 cores. So we'll have to wait and see what core configurationSamsung is going to use for the Exynos 2100. 

In any case, there shouldn't be a performancedisparity between the Snapdragon and Exynos S21 variants which is finally a breath offresh air for Exynos regions. Let me know what do you think down in thecomments and as always I'll see you tomorrow...Peace out!
