The primary feature of Broadwell desktop chips will be Intel Iris Pro 6200 graphics, the highest tier of integrated GPUs offered by Intel. Iris Pro was previously only available on laptop versions of CPUs. Intel says that Iris Pro will give its chips a two-fold improvement in graphics processing capabilities and will also speed up GPU-dependant tasks such as video encoding.
Traditional tower desktops as well as small-form-factor boxes will therefore have better support for 4K video output, gaming, and other graphics-intensive tasks while remaining within a 65-Watt power envelope. Systems with the new processors should be available around the world within 60 days.
On the desktop front, the new models include a Core i7-5775C and Core i7-5775R, both with four cores and eight threads thanks to Hyper-Threading. Both have 6MB L3 caches and run at base speeds of 3.3GHz and burst speeds of up to 3.7GHz and 3.8GHz respectively. While the i7-5775C uses the existing LGA1150 socket, the i7-5775R will be a BGA part.
Similarly, the Core i5-5675C and Core i5-5675R have four cores but no Hyper-Threading, 4MB of L3 cache, and common base and peak speeds of 3.1GHz and 3.6GHz. The final model, the Core i5-5575R runs at between 2.8GHz and 3.3GHz.
While all five desktops CPUs have integrated Iris Pro 6200 graphics, the Core i5 models run slightly slower and support DirectX 11.1 while the Core i7 models support DirectX 11.2. The maximum resolution via DisplayPort tops out at 3840x2160 for the Core i5 models and 4096x2304 for the Core i7 models.
Intel is pitching the mobile versions of its CPUs as ideal for laptops as well as embedded applications such as meducal, public works and industrial applications thanks to the Iris Pro 6200 graphics, support for ECC memory and a guaranteed long lifecycle. Models range from the dual-core Core i5-5350H running at 3.0GHz to the quad-core Core i7-5950QH runnin at 2.9GHz. All have 47-Watt thermal envelopes.
Broadwell processors for ultra-thin laptops and convertible tablets were launched late last year under the Core M name, while slightly more powerful models for small-form-factor devices and thin laptops were announced in January. Today's launches round out the family, though it will be short-lived with the sixth-generation "Skylake" architecture set to launch before the end of 2015.
Intel also announced new 14nm Xeon processors under the E3-1200 v4 name, featuring Iris Pro 6300P graphics for complex HD graphics workloads.
