+ | '''Exynos 8895''' is a {{arch|64}} [[octa-core]] [[ARM]] high performance mobile [[system on a chip]] designed by [[Samsung]] and introduced in mid-[[2017]]. The processor is fabricated on Samsung's [[10 nm process|10nm]] EUV (Extreme Ultra Violet) FinFET process and features [[8 cores]] in a dual-cluster configuration consisting of 4 {{samsung|Mongoose 2|l=arch}} [[big cores]] commonly running at 2314 (but can go up to 2808 MHz with Turbo unlocked), 4 {{armh|Cortex-A53|l=arch}} [[little cores]] at 1690 (Can go up to 2002 MHz with Turbo unlocked). This chip supports up to 8 GiB of dual-channel 16-bit LPDDR4X-1796 memory and incorporates a {{armh|Mali-G71}} MP20 GPU running at 546MHz (But can go up to 839MHz with turbo unlocked). The 8895 incorporates an LTE modem supporting cat 16 download and upload. | ||
+ | |||
+ | == Exynos Turbo == | ||
+ | As far as we know, Turbo frequencies are actually frequencies that the Exynos 8895 could originally go to, but it was limited most likely due to the heating that the Exynos were suffering at the time. | ||
+ | |||
+ | == Exynos ossclk == | ||
+ | The exynos-ossclk is responsible for generating the base frequency for components such as (cpu, gpu, ram, bus, dsp, madera, mif) and also for components outside the SoC like (usb, wifi, camera, pcie). | ||
+ | |||
+ | rate : 26MHz | ||
+ | |||
+ | == Exynos MIF == | ||
+ | MIF is basically the RAM controller its frequency must be parallel with the ram frequency. | ||
+ | |||
+ | rate : 1794MHz | ||
+ | |||
+ | == DSP Devfreq == | ||
+ | DSP is responsible for managing the connection speed between the display and the GPU. | ||
+ | |||
+ | If the DSP frequency is manually manipulated by the user, it will be possible to notice a difference in the fluidity of the display, the change in the maximum and minimum DSP frequencies will alter the data transfer rate sent to the display. | ||
+ | |||
+ | == Madera Devfreq == | ||
+ | |||
+ | Madera is the audio controller chip for the Exynos 8895. | ||
+ | |||
+ | The User manipulation of the Madera frequency may increase or decrease the latency of the speaker audio. | ||

Exynos 8895 is a 64-bit octa-core ARM high performance mobile system on a chip designed by Samsung and introduced in mid-2017. The processor is fabricated on Samsung's 10nm EUV (Extreme Ultra Violet) FinFET process and features 8 cores in a dual-cluster configuration consisting of 4 Mongoose 2 big cores commonly running at 2314 (but can go up to 2808 MHz with Turbo unlocked), 4 Cortex-A53 little cores at 1690 (Can go up to 2002 MHz with Turbo unlocked). This chip supports up to 8 GiB of dual-channel 16-bit LPDDR4X-1796 memory and incorporates a Mali-G71 MP20 GPU running at 546MHz (But can go up to 839MHz with turbo unlocked). The 8895 incorporates an LTE modem supporting cat 16 download and upload.

Exynos Turbo[edit]
As far as we know, Turbo frequencies are actually frequencies that the Exynos 8895 could originally go to, but it was limited most likely due to the heating that the Exynos were suffering at the time.
Exynos ossclk[edit]
The exynos-ossclk is responsible for generating the base frequency for components such as (cpu, gpu, ram, bus, dsp, madera, mif) and also for components outside the SoC like (usb, wifi, camera, pcie).
rate : 26MHz
Exynos MIF[edit]
MIF is basically the RAM controller its frequency must be parallel with the ram frequency.
rate : 1794MHz
DSP Devfreq[edit]
DSP is responsible for managing the connection speed between the display and the GPU.
If the DSP frequency is manually manipulated by the user, it will be possible to notice a difference in the fluidity of the display, the change in the maximum and minimum DSP frequencies will alter the data transfer rate sent to the display.
Madera Devfreq[edit]
Madera is the audio controller chip for the Exynos 8895.
The User manipulation of the Madera frequency may increase or decrease the latency of the speaker audio.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
