Samsung Galaxy Note 4 Exynos Review It been over three months since Josh had the opportunity to review the Note 4 in its details. The defining characteristic goyar coque iphone of that review is that it was a look at the variant with Qualcomm Snapdragon 805 SoC running at the heart of the device. This version is found in devices shipping in North America, Western Europe, China and Japan. iphone 11 case coque samsung galaxy a3 While these markets have now been served by Qualcomm silicon offerings, Samsung is now back on track at trying to expand coque huawei p8 lite 2017 avant arriere its market share of in house Exynos SoCs. As such, all other markets (with small exceptions) seem to be getting served Exynos variants of the Note 4. While we normally try to cover all aspects of device performance, for this review we will focus on the SoC and the differences that result from this change. coque iphone The model breakdown of the Note 4 is quite a mess. The S805 version breaks down into about 9 different local versions, each with different RF frequency support and varying modem configurations. The Exynos variants are even more convoluted coque huawei mate 20 pro loup in coque iphone se coque huawei y5 ii garcon gold terms of modem choice. We been reporting that we might see Intel XMM7260 as the predominant modem in Samsung SoCs, but that seems to have changed and the Intel modem is only coque iphone 7 silicone pas cher shipped in a small percentage of total units on the SM N910U model, which ships in South East Asia. In their home country of Korea Samsung continues to rely on their own modem, recently marketed as the «Exynos Modem» series. Samsung has been steadily developing their own modem hardware over the coque iphone se qlf years and it seems the M303 is coque iphone 5s coquine at feature parity with the Intel XMM7260 and Qualcomm MDM9x35. coque iphone This year Samsung has been pushing their modems outside of Korea in several devices such as coque iphone se pasteque the Galaxy S5 Mini, so I expect them in the future to be more prevalent in other global markets. The surprise supplier yellow jacket coque iphone and apple store coque iphone 7 big winner of this generation is Ericsson; the M7450 is found in unarguably the largest portion of Exynos variants, the SM 910C and SM 910H, shipping throughout South America, Central and Eastern Europe, Africa, the Middle East, and some Asian countries. Brian first reported on this modem over 1.5 years ago and we haven heard much about it since. The surprise here is that Ericsson managed to get such a big design win before announcing that they will discontinue development on modems altogether. The even more intriguing story is that the M7450 is used in the 3G version of the Note 4, usually a traditional Intel design win. Whatever model you end up with, and as long as the frequency bands match your provider, the choice between Snapdragon and Exynos remains the biggest differentiation. Everything else from camera to WiFi to battery size coque huawei p8 lite koala remains the same in an identical form factor. Exynos 5433 The First Mobile ARM A57 SoC I had reported back in September coque iphone 5s pirelli that Samsung new Exynos 5433 found in the Note 4 is actually the first implementation of ARM A53/A57 and T760 new SoC IP. While it took Samsung some time to actually officially announce the part, they eventually did confirm it. collier argent The interesting disclosure here is that they choose to market it in the Exynos 7 family, which certainly makes more sense than keeping it in the Exynos 5 category of SoCs. Also in my initial article I shared my opinion that I doubted that Samsung would update the Note 4 to AArch64 this was based on the fact that the kernel treats the SoC as an A7/A15 part and most of the software stack remained 32 bit. Events since then seem to point out that they will eventually upgrade it to 64 bit, since coque iphone 5c bob razowski we seeing official patches in upstream Linux with the chip being introduced with a full ARMv8 device tree. This is interesting to see and might point out that Samsung will go the effort to upgrade the BSPs to AArch64; however it remains unclear whether we see this on the Note 4. My personal opinion remains that we won be seeing this overhaul in Samsung 5.0 Lollipop update. Let take a coque samsung j5 look again at how things have evolved in terms of spec sheet since then: I been able to confirm that the GPU on the 5433 is an MP6 configuration, meaning it sports the same amount of cores as the previous Mali T628 implementations in the 5430, 5422 and 5420. I also acquired a Galaxy Alpha which I review at coque huawei p8 lite 2017 punk a later date, but noticed that Samsung is also shipping 825MHz memory on that device. As such, the bandwidth of the 5430 is corrected from the publicized 17GB/s down to 13.2GB/s. Samsung has retained the cache sizes found in the older 54xx SoCs, meaning 512KB on the little cluster We see a reduction to 256K on the L2 of the A53 cluster, and a continuation of 2MB on the big cluster. I would have liked to see the A53 getting 1MB of L2 but it seems we have to wait for future SoCs to see an improvement there. In other regards, the 5433 differs very little from the 5430. It has almost identical auxiliary block IP, sharing the same ISP, hardware decoders and encoders, various interfaces, and a similar bus architecture. Correction 24/03/2015: Our initial info of 512K L2 cache on the A53 cluster was wrong and has henceforth been corrected to 256K (Source) With the modem and SoC platform being the two coque iphone 6 porsche design main differences between the two Samsung devices, there are some other minor changes of components. On the audio side Qualcomm WCD9330 is replaced by WolfsonMicro WM5110 audio SoC. coque samsung The Wolfson IC uses its integrated DSPs for voice processing, replacing the need for an coque iphone 5c non additional Audience eS705 audio processing chip that is used in the Snapdragon variant. This might result in different call and audio quality between the two versions. The WM5110 also takes over device voice activation duties for the Exynos Note 4, which you can use with SVoice or Google coque huawei huawei mate 20 lite Now. I also noticed that yet again Samsung did not allow for native 44.1KHz audio playback in the default configuration of Android AudioFlinger on the Exynos version, causing forced resampling of 44.1KHz content to 48KHz. Neither version allows for higher quality output, even coque samsung galaxy s9 though both audio solutions support 24 bit 192KHz audio in hardware. I not sure what Samsung audio team is doing here but it getting increasingly frustrating to coque iphone 6 strass paillette see this issue continue, starting with the Galaxy S4. In terms of media playback, Samsung has not exposed the HEVC/H265 hardware decoder of the Exynos 543X to the media codec capabilities list of the system. The device is still shipping with the decoder block firmware, so again this is either an oversight or something has gone wrong during development of the device. The Qualcomm version exposes the HEVC decoder of the Snapdragon 805. A large functional difference between recent Exynos SoCs and Qualcomm variants comes with the capability of the display controller. Due to 1440256032bpp60fps picture bandwidth exceeding the transport capacity of a 4 lane MIPI DSI link from the SoC display controller to the display driver, Qualcomm devices need to double up on this interface and use dual DSI links. The Qualcomm S805 uses two DSI ports with 4 lanes each to drive the display in halves of 720×2560 pixels, while the Exynos SoCs since the 5420 are able to make do with just a single 4 lane port with help of Mobile Image Compression. MIC compresses the data stream and thus avoids this bandwidth bottleneck. The disadvantage here is that the display driver itself must be able to decompress the stream. With Samsung developing their own AMOLED display drivers they can however take advantage of this vertical coque iphone se automne integration and implement this in their phones and tablets. The power advantages here can vary up to 150mW if the image stream is able to be highly compressed, or about 100mW on average. This of course has the biggest impact on highly dynamic content, as static content power consumption has mostly been resolved by Panel Self Refresh, which has seen wide adoption over the last coque samsung galaxy s7 edge 18 months. ddriver Thursday, February 12, 2015 link Also in true 64bit mode, cuz a lot of the perf improvements in v8 are not available in legacy 32bit mode. It is a shame really, samsung decided the uArch improvements would be enough to barely pass this chip as «incremental», they didn bother to feed a higher throughput chip with a wider memory bus. And let’s not pretend Apple’s CPUs sucking wouldn’t invite the same kind of comments just like every situation where 2 competing technologies are compared. Platform/fanboy trolling aside, that’s something Android users benefit from as well. bracelet bijoux Apple being «stubborn» about 2 core CPUs, for example, is a nice counterweight to the 8 cores and 8 mini cores and 8 quasi cores trend that some CPU vendors seem to have a hard on for, and it gives a nice real world example of how such an approach to mobile CPU design works out, no If Apple stays ahead in the mobile CPU game, the people using non Apple phones will always have a target to point to and demand equality with.
