The Uncontested Rapper Speed Battle: 5 MCs Faster Than Eminem (And Who Holds The Real World Record)

The debate over the "Fastest Rapper in the World" is one of hip-hop's most enduring and fiercely contested arguments, often boiling down to a technicality: the difference between an official chart record and pure, raw speed. As of late 2024, the title is split, with the legendary Eminem holding the most recognized *Guinness World Record* for a hit single, while a handful of underground and international MCs boast speeds that are mathematically—and audibly—faster. This deep dive uncovers the true speed demons of the mic, breaking down the Syllables Per Second (SPS) metrics that separate the speedsters from the legends. The conversation is complex, involving not just Words Per Minute (WPM) but also the intricate rhythm of double-time flow and the geographical subgenre known as "Chopper Rap." While Marshall Mathers, better known as Eminem, set a monumental benchmark that may never be broken on a number one single, the history books and the underground scene reveal a list of artists whose vocal dexterity pushes the absolute limits of human speech.

The Official Guinness World Record Holder: Eminem's Unmatched Chart Speed

While many rappers have achieved incredible speed in their careers, only a few have had their technical prowess officially documented and certified by the global authority on records. Eminem has cemented his place in history by breaking his own records, making him the undisputed king of commercially successful speed-rapping.

Eminem: The King of Chart Speed

• Real Name: Marshall Bruce Mathers III
• Born: October 17, 1972 (Age 52 as of 2024)
• Origin: St. Joseph, Missouri, USA
• Key Speed Tracks: "Godzilla," "Rap God," "Majesty"
• Record-Breaking Speed (Godzilla): 10.65 Syllables Per Second (SPS)
• Guinness World Record: Fastest Rap in a No.1 Single

Eminem's record-breaking moment came with the 2020 track "Godzilla," featuring the late Juice WRLD. In the third verse of the song, Eminem rapped a staggering 225 words in just 30 seconds. This translates to an average of 7.5 words per second, or a blistering 10.65 syllables per second (SPS). This feat broke the record he previously set with the 2013 hit "Rap God," where he delivered 1,560 words in 6 minutes and 4 seconds. The "Godzilla" record is specific—it is the fastest rap verse *in a number one single*—a qualification that separates it from the overall speed records claimed by others.

The Speed Demons: 4 Rappers Who Claim Faster Overall Speeds

The true fastest rapper title is often claimed by artists who specialize in the technical delivery of "double-time" or "chopper" rap, a style that prioritizes speed and syllable articulation over traditional narrative flow. These speeds are often calculated by fans or analysts and may not hold the same official certification as a Guinness record, but their numbers are undeniably higher.

1. Crucified (Claimed 28.9 SPS)

The Texas-based rapper known as Crucified is frequently cited in the underground community as the fastest rapper alive, with a claimed peak speed that dwarfs all others. He is reported to have reached an astonishing 28.9 syllables per second on his track "Power Up." In 2013, he also attempted to break the Guinness World Record, rapping 949 syllables in 49 seconds. While this speed often lacks the official verification of a global body, the sheer volume of syllables articulated per second makes him a formidable, if less mainstream, contender.

2. Outsider (Claimed 24 SPS)

Hailing from South Korea, Outsider (real name Shin Ok-cheol) is a global speed-rap phenomenon. He is a prime example of how rap speed transcends language barriers. Outsider has been recognized for consistently rapping at speeds over 17 syllables per second, with peak claims reaching 24 syllables per second in some of his verses. His track "Loner" is a masterclass in breath control and rapid-fire delivery, solidifying his status as a technical powerhouse.

3. Rebel XD (Former Guinness Record Holder)

Before Eminem claimed the chart-topping speed record, the title for the overall fastest rapper was often held by Chicago's Rebel XD. He held the Guinness World Record multiple times, with one of his most famous records involving the delivery of 852 syllables in 42 seconds, which is an average of approximately 20 syllables per second (SPS). This raw speed is significantly higher than Eminem's certified chart record and places Rebel XD among the elite speedsters of all time.

4. Twista (Former Guinness Record Holder)

Twista is arguably the original speed-rap pioneer who brought the "chopper" style to the mainstream. Hailing from Chicago, he was the first to be officially recognized by Guinness World Records in 1992 for being the fastest English-speaking rapper. His record involved pronouncing 598 syllables in 55 seconds. While subsequent rappers have surpassed this metric, Twista's flow in tracks like "Worldwide Choppers" and "Mista Tongue Twista" remains a foundational benchmark for all fast rappers.

The Science of Speed: Chopper Rap and Double-Time Flow Explained

The ability to rap at extreme speeds is not just about moving the mouth quickly; it is a highly specialized vocal technique that requires incredible breath control and rhythmic precision. The fastest rappers in the world utilize specific flows and subgenres to achieve their mind-boggling speeds.

What is Chopper Rap?

The term "Chopper Rap" or "Chopper Style" is a subgenre of hip-hop that originated in the Midwestern United States, particularly in cities like Chicago and Kansas City. It is defined by its exceptionally fast-paced delivery, featuring rapid syllable articulation and, most importantly, double-time flows.

The style gets its name from the rapid, almost machine-gun-like delivery of the lyrics, reminiscent of a helicopter's blades. Key practitioners of the chopper style include Twista, Tech N9ne, Krayzie Bone, and the collective known as Bone Thugs-N-Harmony.

Mastering the Double-Time Flow

Double-time flow is the fundamental technique used by all speed rappers. In simple terms, it means rapping at twice the speed of the song's instrumental beat (BPM, or Beats Per Minute).

• Normal Flow: A rapper might deliver one or two syllables per beat.
• Double-Time Flow: The rapper delivers four or more syllables per beat, effectively dividing the musical bar in half and filling the space with double the words.

This technique creates a dramatic, high-energy effect, often used to build tension before a pause or a return to a normal pace. Eminem’s verse in "Godzilla" is a perfect example of a sustained, high-speed double-time flow.

The Secret Weapon: Breath Control Techniques

No matter how fast a rapper can move their mouth, the true limiting factor is the ability to sustain the flow without taking a breath. The fastest rappers are essentially vocal athletes who have mastered advanced breath control.

Diaphragmatic Breathing

Unlike shallow chest breathing, speed rappers utilize diaphragmatic (or belly) breathing. This technique allows the lungs to take in a greater volume of air, providing a larger reserve to power the rapid, sustained vocalization needed for double-time flows. Practicing deep, controlled inhales and slow, steady exhales is a core exercise for improving rap stamina.

Strategic Phrasing

The most skilled speed rappers are masters of lyrical architecture. They don't just write fast; they strategically place small, quick pauses in the rhythm where the beat naturally allows for a fraction-of-a-second inhale. This allows them to "steal" a breath mid-verse without breaking the illusion of a continuous, breathless flow. By rapping slowly and carefully, then gradually speeding up, a rapper can identify the optimal spots for these quick, vital inhales.

Conclusion: The True Fastest Rapper in 2024

The title of "Fastest Rapper in the World" depends entirely on the metric you use. If you are looking for the most famous, officially certified, and commercially successful speed-rap record, the winner is still Eminem, with his 10.65 SPS in "Godzilla." However, if the title belongs to the MC who has achieved the highest *raw* syllable count per second, then the crown is likely held by an underground specialist like Crucified (claimed 28.9 SPS) or former record holder Rebel XD (20 SPS). The debate continues to evolve, but one thing is clear: the technical boundaries of what is possible with the human voice are constantly being pushed by the world's most gifted and dedicated MCs.
