How To Fix Broken S7 Back Glass

Samsung'south new Milky way S7 and S7 Edge smartphones will sport either the company's homegrown Exynos or Qualcomm'due south Snapdragon processor, depending on where you purchase it. What'southward the difference between the chips, and which one will your Galaxy model accept?

If you're in the U.S., information technology'll be a Qualcomm Snapdragon chip, a Samsung spokesman said, without revealing farther details. It'southward almost an open up clandestine that the chip volition be the Snapdragon 820, designed for premium handsets.

Countries in Europe and Asia volition probable go models with the Exynos scrap, possibly the Exynos 8 Octa 8890, which was announced by Samsung late last year.

The new smartphones volition ship on March 11, and initially be available through carriers. Samsung said it volition not sell an unlocked version of the phone, though a spokesman acknowledged some unlocked handsets could be available in the grey market.

The Snapdragon 820 has faster graphics, CPU and LTE speeds compared to its predecessor, the 810. Samsung dropped the Snapdragon 810 from its Samsung Galaxy S6 due to overheating problems. The program to bring the improved Snapdragon to the S7 should close the door on what turned out to exist a public-relations hit for Qualcomm.

Both the Samsung and Qualcomm chips are acme-line processors and offering strong graphics and awarding performance. Samsung has promised that all versions of the S7 models will offer 30 percent faster CPU performance and 64 percentage faster GPU performance than the S6. The smartphones have larger batteries than their predecessors, and the more ability-efficient chips should boost run-time on a unmarried charge.

The company is using the two fries largely considering they have different integrated modems. The Snapdragon 820 modem supports a wider range of bands and runs on older CDMA networks operated by companies like Verizon. The Exynos is tuned for GSM and LTE networks deployed in European and Asian countries.

So why didn't Samsung put Qualcomm'southward chip in all Galaxy S7 and S7 Edge handsets? The homegrown Exynos chip is cheaper for Samsung to integrate in its handsets, said Jim McGregor, an analyst at Tirias Research.

Carriers besides influence the chip decision in some cases, simply the Snapdragon 820 is expensive because information technology's a premium processing unit, McGregor said.

The chips are tied to cellular engineering science and spectrum use in different countries. Qualcomm's chip is tuned for carrier aggregation in the U.S., in which data transfer speeds could receive a big heave by aggregating bandwidth from multiple bands and carriers. This technology is helpful for dual-SIM handsets with connectivity to 2 carriers. Samsung'south Exynos as well supports carrier aggregation, but it is optimized to work on specific networks.

The data-transfer rates from the modems are the aforementioned, with download speeds of upward to 600Mbps (bits per second), and upload speeds of 150Mbps. The Snapdragon chip is more than versatile because it is amid the first to support LTE-U, in which faster information transfers can accept place over both licensed and unlicensed spectrum.

The Snapdragon 820 will come in quad-cadre configurations, while the Exynos could have up to eight cores. The Snapdragon 820 besides supports WiGig wireless applied science, which is roughly up to three times faster than Wi-Fi in wireless data transfers, merely that feature could exist shut off so the handsets requite customers similar speeds.
