It runs at speeds of 25, 33, and 40 MHz.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p><p>The 486DLC can be described as a 386DX with the 486 instruction set and 1 KB of on-board <a href="/wiki/L1_cache" class="mw-redirect" title="L1 cache">L1 cache</a> added. Because it uses the 386DX bus (unlike its 16-bit cousin, the <a href="/wiki/486SLC" class="mw-redirect" title="486SLC">486SLC</a>), it is a fully <a href="/wiki/32-bit" class="mw-redirect" title="32-bit">32-bit</a> chip. Like the 386 and 486SX, it has no on-board math <a href="/wiki/Coprocessor" title="Coprocessor">coprocessor</a>, but unlike the 486SX, it can make use of an Intel 387DX or compatible numeric <a href="/wiki/X87" title="X87">x87</a> coprocessor. Due to the smaller L1 cache, the 486DLC can not compete on a clock-for-clock basis with the 486SX, but a 33 MHz 486DLC can keep pace with a 25 MHz 486SX, cost less, and offers the ability to upgrade further with the addition of a math coprocessor. </p><p>While advertisements from smaller manufacturers touted the superiority of their 486DLC over name-brand computers sporting a 486SX, the only advantage the 486DLC offers over the 486SX is the ability to add a math coprocessor. The Intel 487 "math coprocessor" for 486SX users is a CPU replacement—a 486DX with a different pinout—and originally cost several hundred dollars more than a 387. </p><p>As prices on Intel's 486 line fell, Cyrix found it more and more difficult for its 486SLC and DLC CPUs to compete and released a fully pin-compatible version of the 486SX and DX in 1993. </p><p>The 486DLC did not see widespread use among large OEMs, but it was widely known among the hardware enthusiast community that an <a href="/wiki/Am386" title="Am386">AMD 386DX-40</a> or Cyrix 486DLC-33 could keep up with a 486SX-25 at a lower cost, so it gained a small following among budget-minded enthusiasts. It was also sometimes used as a replacement for a 386 CPU to give a small speed boost. However, the 486DLC was not designed to be a direct CPU replacement and could lead to stability problems in older boards it was not intended for. "Cyrix-aware" motherboards usually had a few extra cache control lines to maintain cache coherency, as well as CPU register control in the BIOS to enable/disable the on-board cache. Cyrix later released a clock-doubled "direct replacement" upgrade package for 386DX systems called the Cx486DRu2. This kit included a standard 486DLC with an extra "dingus" that sits between the CPU and <a href="/wiki/CPU_socket" title="CPU socket">socket</a> and provides the control lines for cache coherency. These kits were quickly superseded by the Cx486DRx2 CPU, which integrates the cache coherency circuitry into the CPU itself. The Cx486DRx2 appeared on the market in 1994, by which time the 486 was already being displaced by the Pentium. Sales were poor due to the high price and the underwhelming performance compared to a true Intel 486DX2. It was often cheaper to purchase a new 486 motherboard than to invest in an upgrade CPU.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span
