Like the Speedometer 2.0 benchmark, this is heavily reliant on both CPU and memory performance – and extra memory really helps some of the models on test. For Raspberry Pi models with more than one processing core – the Raspberry Pi 2 and 3 family, and Raspberry Pi 4 – the test is run a second time using the multi-threaded lbzip2.Īnother real-world test, the popular open-source GIMP image-editing suite is used to process a high-resolution image and save it as a PNG.

The new VideoCore VI gives Raspberry Pi 4 a significant boost over its predecessors, as demonstrated in this gaming workload test: the Quake III-based OpenArena first-person shooter runs through its built-in demo as quickly as possible at a High Definition (1280×720) resolution, while the average frame rate in frames per second (fps) is recorded.Īlthough many workloads are primarily limited by CPU speed, others rely on memory bandwidth – the rate at which data can be written to and read from RAM. Here, performance hinges not only on CPU performance but on memory speed and capacity – the test proved too much for Raspberry Pi A+. Speedometer 2.0 measures the responsiveness of the Chromium web browser by running a web application – a to-do list – and measuring how many times the application can be completed each minute. This version – ported by Roy Longbottom – comes in three variants: the fast single-precision (SP), slower double-precision (DP), and a single-precision variant accelerated using the NEON instructions available in Raspberry Pi 2 and above (NEON). Raspberry Pi 4 Benchmarks Linpack (CPU speed test)Ī synthetic benchmark originally developed for supercomputers, Linpack offers a glimpse at just how far the Raspberry Pi family has come. Two USB 3.0 ports, centre, offer high-speed connectivity for external devices including storage and accelerator hardware. The Ethernet port, relocated to the top-right of the board, now offers full-speed network connectivity with no bottlenecks. The two micro-HDMI connectors enable Raspberry Pi 4 to drive two 4K displays at up to 4Kp30, or a single display at up to 4Kp60 The new BCM2711B0 system-on-chip offers an impressive performance boost over its predecessors.

Raspberry pi 4 model b connectors upgrade#
The brand-new BCM2711B0 system-on-chip has more powerful processing cores, the first upgrade to the graphics processor in the history of the project, and vastly improved bandwidth for both memory and external hardware. It's not hard to see where this benchmark boost comes from. Our Raspberry Pi 4 benchmark tests show a huge increase in performance over previous models. Raspberry Pi 4 improves on its predecessor, with improved specifications across the board.
