First Pentium 4 microprocessors, based on Willamette and Northwood cores, as well as some Prescott processors, were referenced by their speed. A - Northwood microprocessors with 512 KB L2 cache (for frequencies 2 GHz and lower), or Prescott CPUs with 1 MB L2 cache (for frequencies higher than 2 GHz).
What is a Superficial Blood Clot? When blood clots in the superficial veins of the leg, it is known as a superficial thrombophlebitis (or commonly, phlebitis). Patients often may experience pain and tenderness on the surface of the leg with appearance of a tender lump or streak. Many times, patients recall a varicose vein in the same area prior to the phlebitis appearing. Varicose veins are a well-recognized risk factor for superficial thrombophlebitis. While phlebitis confined to the surface veins does not pose the same serious risk as DVT, we know that some patients with phlebitis progress to DVT as that surface clot extends to the deep venous system.
Bruise-related clotting happens in tissue outside the blood vessels. Thatâs where the bleeding occurred. What youâre really worried about is a deep-vein thrombosis (DVT)âa clot that forms inside a deep-in-the-tissue vein and can break off and travel to the lungs. DVTs are different, serious, and sometimes lethal. So a bruise isnât a serious blood clot. However, can a bruise cause a serious blood clot? No, but the hit that caused the bruise canâthough thatâs rare. If the trauma that caused the bruise injures a large and deep-seated veinâs wall, it could make conditions right for a deep-vein clot to form.
