Snapdragon 835, Everything You Need to Know

0

Qualcomm’s new Snapdragon 835 is finally upon us, so, here’s what we already know about the chip, specs, speed, cores and more. Qualcomm dropped the ball in 2015 with the Snapdragon 810 ( a failure). Again they Launched Snapdragon 821 and 820 with custom made Kryo cores on board. Snapdragon 835 follows similar steps and there's a lot more, Read on!

"Sony has confirmed that its new Sony Xperia XZ Premium smartphone – announced at MWC 2017 – will carry Qualcomm's Snapdragon 835 chip."

The Snapdragon 821 and 820, by comparison, were built using a less efficient 14nm manufacturing process. The bottom line is that the 10nm design allows the Snapdragon 835 to be more powerful and more efficient than older chips.

What makes 10nm better than 14nm?

The chip contains a circuit and transistors. Transistors are like tiny electronic switches that allow computer systems to get things done. The more transistors you have, the more things you can get done in parallel, i.e. at a given time.

"Putting more transistors on a chip will make that chip more Powerful."

The term ‘10nm’, is a physical distance: 10 nanometres. What it really means is the distance between a feature on one transistor, and the same feature on the transistor next to it. It’s an easy way of describing how far transistors are apart, or rather how densely they’re packed together. So, transistors on a 10nm chip can fit more transistors onto the circuit (Better Performance).

"The premium Snapdragon 835 processor was designed from the ground-up to support new and innovative products and experiences beyond mobile phones. And it's great to see that the first announced Snapdragon 835 devices will be ODG's smartglasses," said Raj Talluri, senior vice president, product management, Qualcomm Technologies.

"Thermal dissipation on a heavy compute but small device is very difficult so higher power efficiency is a must," continued Talluri. "The Snapdragon 835 processor, with our unique SoC design expertise on a 10nm process node, enables ODG to meet their design goals and develop lighter, smaller and sleeker smartglasses that take advantage of the new processor's superior performance and power efficiency.

“We are pleased to have the opportunity to work closely with Qualcomm Technologies in producing the Snapdragon 835 using our 10nm FinFET technology,” said Jong Shik Yoon, who heads up Samsung’s foundry business.

Specs and More

The key specs of the latest Snapdragon chip was also leaked recently and is revealed to use an upgraded version of the 64 autonomous Kyro 200 architecture with four large and four small octa-core design.

Processing:

The Snapdragon 835 features two sets of four Kryo 280 cores each. These are clocked at 2.45GHz and 1.9*GHz for the higher and lower performance clusters. The Kryo 280 cores are different from their predecessors in more than their name. This year, the Kryo cores are based on an unspecified ARM design.

Qualcomm hopes that 10nm will do its work for performance and that up to 80% of the workload on the Snapdragon 835 will be performed by the 1.9GHz core cluster. At the processing end, the company promises a 20% boost over the Snapdragon 820. The processor is said to offer a blazing download speed of up to 1Gbps.

An interesting feature on the Snapdragon 835 is different cache sizes. The higher performance core cluster gets 2MB of L2 cache and the lower performance cluster gets 1MB of cache. Power efficiency, rather than hardcore performance is Qualcomm’s concern on the Snapdragon 835.

Graphics:

The Snapdragon 835 is listed as using the new Adreno 540 GPU which would likely give it a superior graphics performance. The chip also integrates LTE X16 baseband and supports LTE Cat.16. The GPU will increase support to 107 million colors, from 17 million on the Adreno 530. It’s a 64x increase, that will allow developers to include support for HDR10 and allow for crisp and detailed image/video capture.

The Adreno 540 also supports 25% increase in 3D rendering over the Adreno 530 and allows for faster trilinear filtering and GPGPU processing. The Adreno 540 will also come with improved display rates. That will end up smoothing frame rates and overall display outputs. For the Adreno 540, display refresh rate will be qual to the GPU frame rate.

That's all for today!
