Since the PlayStation 4’s release in North America a few days ago, we are confident that technology bluffs are eager to see what’s inside. You may find several PlayStation 4 tear-off articles around the internet but our piece will go even deeper into the PlayStation 4’s architecture, outlying the various components and their respective specifications. Therefore, if you are interested in learning more about the PS4’s internal workings, this article might be right for you. ps4 amd
RAM:
The PlayStation 4 has 8GB of GDDR5 RAM and an eight-core x86-based CPU. Since the PlayStation 4 was unveiled in February of this year, developers have praised the latter in unison. This 8GB is divided into 16 512MB DRAM modules, eight of which are located above and eight below the CPU. The RAM that Sony uses is the Samsung K4G41325FC model, which has a refresh rate of 16K/32ms per 4GB. The K4G41325FC model, which Samsung refers to as fixed and permanent memory, is known to boost GPU performance. The latency in GDDR5 is not particularly high when compared to DDR3. GDDR5’s latency shouldn’t be a big deal because GPUs are designed to be somewhat latency independent. Additional Chip: The PlayStation 3 had some limitations when it came to running two applications simultaneously. That is all set to change with the PlayStation 4. It features Samsung’s K4B2G1646E-BCK0 which is a 2Gb [not Giga Bytes, it is Giga Bits] DDR3 SDRAM secondary chip. This model is a 16Mbit x 16 I/Os x 8 banks device with transfer rates of up to 2133Mb/sec/pin. This amounts to roughly 256 MB of DDR3 SDRAM, which is incredible considering that the PS3 had the same amount allotted for video and the operating system. ps4 motherboard

Serial Flash Memory:
The PlayStation 4 features a Macronix MX25L25635FMI 256Mb Serial Flash Memory. We don’t know for sure what this memory will be used for, but we think it will be used to store the 15-minute clips that were recorded and the screenshots that were taken on the fly with the Share button. Additionally, the PlayStation 4 has two Macronix MX25L1006E CMOS Serial Flash Memory, one on the motherboard’s back and the other close to the USB port. It is a 1,048,576-bit serial Flash memory that is internally arranged as 131,072 x 8. CPU and GPU:

The PlayStation 4 features a custom built AMD solution for its unified GPU and CPU. The die, which bears the designation CXD90026G SoC and measures 348 square millimeters in size, is significantly larger than the PlayStation 3. It consists of 20 compute units, two of which are redundant to increase yield, and 1152 shader processors which should place it comparatively between AMD Radeon HD 7850 and 7870. The custom chip uses Taiwan Semiconductor Manufacturing Company’s 28-nm high-k transistors.
Ethernet Controller:
The PlayStation 4 uses the Marvell Alaska 88EC060-NN82 model, which is similar to the one found on the PlayStation 3.
